Clipit: Hot keys not working since 1.4.4-2 on Debian testing 64-bit

Same problem here.. I've done a little investigation and found out that it throws some errors instead showing GUI. Unfortunately I wasn't able to solve them.

(clipit:7183): GLib-GObject-CRITICAL **: 20:56:43.530: g_object_set_data: assertion 'G_IS_OBJECT (object)' failed
(clipit:7183): Gdk-CRITICAL **: 20:56:43.530: gdk_window_get_window_type: assertion 'GDK_IS_WINDOW (window)' failed

Update: There is another issue thanks to this hotkeys' complexity.

When you go to Manage History and delete a line from your history, by revisiting your Manage History you can see the line retaining its space, but without the actual string in it.

As soon as you delete the empty line, it automatically deletes the immediate next line.

This behavior is rather critical in my humble opinion.

Same issue in my case (Debian testing)

Hi, same issue here :

The history pannel is like this, and the preferences panel is freezed after a first click inside it, also the hotkeys to access history clipboard doesn't work anymore...

Some logs :

System informations

uname -a :
Linux oab-cycd9w1 4.17.0-1-amd64 #1 SMP Debian 4.17.8-1 (2018-07-20) x86_64 GNU/Linux

cat /etc/debian_version : buster/sid

Temporary solution

Since i didn't see any news about a potential fix, I removed my clipit version and switch to the 1.4.2 version for the strethc repository.

If you also need this, here is the steps :

1. Check the different version you can install

$ apt-cache policy clipit
clipit:
  Installed: 1.4.2-1.2
  Candidate: 1.4.4-2
  Version table:
 *** 1.4.4-2 900
        900 http://http.debian.net/debian buster/main amd64 Packages
        -10 http://http.debian.net/debian unstable/main amd64 Packages
     1.4.2-1.2 100
        -20 http://httpredir.debian.org/debian stretch/main amd64 Packages
        100 /var/lib/dpkg/status

(in my case i'm on Debian testing, so i installed the 1.4.4-2 version of clipit from 'buster/testing' repository)

1. Then remove clipit (don't purge it, you will loose all your preferences)
   $ sudo apt autoremove clipit

2. Now install again clipit but from the repository you want, in my case 'stretch/stable' repository
   $ sudo apt install -t stretch clipit

3. Finally, check the installed version :

$ apt-cache policy clipit
clipit:
  Installed: 1.4.2-1.2
  Candidate: 1.4.4-2
  Version table:
     1.4.4-2 900
        900 http://http.debian.net/debian buster/main amd64 Packages
        -10 http://http.debian.net/debian unstable/main amd64 Packages
 *** 1.4.2-1.2 100
        -20 http://httpredir.debian.org/debian stretch/main amd64 Packages
        100 /var/lib/dpkg/status

Enjoy, you will now be able to launch again clipit without a freezed preference panel and with an hotkey working. (and everything else)

I have the same problem, but could not reproduce the error when custom building from the debian package source directory (https://salsa.debian.org/debian/clipit.git). Looks like it is an issue of the build itself...

@swillner When you say custom building, what exactly did you change comparing the original build?

I build directly from the debian source repo (using ./autogen.sh and ./configure as in the documentation). So ok, "custom" only in the sense of building myself on my machine ;)

@swillner ah OK, cool. Hmm...I wonder what's causing this problem with the existing package.

Hi!

glib2 is 2.56.1-1

Same issue with version 1.4.4-2 after upgrading Ubuntu from 18.04 to 18.10. Temporary fixed by reinstalling lower version (1.4.2-1.2) of ClipIt from pkgs.org

I got similar errors as @emjayko:

(clipit:7183): GLib-GObject-CRITICAL *: 20:56:43.530: g_object_set_data: assertion 'G_IS_OBJECT (object)' failed
(clipit:7183): Gdk-CRITICAL *: 20:56:43.530: gdk_window_get_window_type: assertion 'GDK_IS_WINDOW (window)' failed
```

I found out, that if I hold the hotkey long enough, the history window appears.

Exact same issue for me with the latest master (looks like version string has been updated to 1.4.5), built with --with-gtk3. There were some deprecation warnings during configure but it finished fine.
There's definitely been some recent improvements because even compiling wasn't completing for me a few months ago.

But I guess this particular issue is still to be fixed.

I found out, that if I hold the hotkey long enough, the history window appears.

THANK YOU!

I now have this issue in Debian Stable 10 … unsurprisingly I guess. ClipIt version 1.4.4 from debian buster repo. Problem exactly as described above, hotkeys do not work. Terminal shows error:
(clipit:1000): Gdk-CRITICAL **: 19:03:32.292: gdk_window_get_window_type: assertion 'GDK_IS_WINDOW (window)' failed when hotkey is pressed.

Possibly related: If I interact with the tray icon and pull up preferences, about, etc. they work fine. However if I try to use, for instance the History hotkey (as usual nothing happens on key press), but if I then try to open one of the dialogue/windows such as preferences or the about page, etc I will get a small black rectangle in the upper left portion of my screen, the intended window never appears and ClipIt must be killed to get rid of the black rectangle.
Behavior is the same using jwm or fluxbox.

So is this project dead or what? Completely broken across many distributions and not a peep :(

I cannot speak for the ClipIt project in any way and cannot comment on whether the project has any life in it at this time or not. For what it's worth, I personally have moved over to using GPaste. Which is in the Debian repos and works very well. I post this, not to impugn the ClipIt project in any way, or even to claim that GPaste is the best alternative (indeed, there seem to be many) … but only in the hopes that it may help users who are presently encountering a functionality breaking issue and looking for a relatively quick & painless fix.

Thanks, @J-Reis. Personally I've settled on Clipman (provided by _xfce4-clipman_ package) -- lightweight, stable and DE-neutral.
_GPaste_ is too GNOME-centric for those who prefer other Desktop Environments...

I hesitate to continue hijacking this thread discussing replacements, but I'm not sure what you've said is really true. I'm not running gnome, just a window manager on top of X and I don't recall GPaste pulling in a significant number of dependencies. Of course, I habitually choose the application that works best for me—I don't disregard anything solely on the basis of what libraries it uses, so perhaps my system is just massively bloated and all those Gnome dependencies were already present. Since I'm no expert, I just did a quick check of dependencies using apt (obviously the specifics are a bit Debian centric, but the general trend should hold regardless of system):

Do let me know if I'm failing to understand something here, I'm always trying to learn!

Seems like we have some progress...

On my system, version 1.4.5 is installed and when I press Ctrl+Alt+F, I get a popup window to search my clipboard.

If I press Ctrl+Alt-H though, it behaves as my original report.

fwiw I liked the project and it did everything I wanted, but I've moved on to parcellite, which is worse but better because it works. :/

I get that it's OSS and we're all busy people, but I'm honestly pretty confused that this change wasn't just rolled back. "Hotkeys don't work" is a showstopper.

Where dou you got the 1.4.5 Version from? Have not seen any release yet.
I ve just upgraded from Ubuntu 19.04 to 19.10 and installed / downgraded to clipit_1.4.2-1.2_amd64.deb which unfortunately does not work anymore as in 19.04.
So either I find this 1.4.5 Version or I need to use another Clipboard Manager since working without one seems to be a nightmare!f

Please read my ticket's title.

When I use gdb to debug this issue, I found that if a create a break point at create_history_menu, and just continue to run after break stopped, everything goes fine, but I have no idea about it, I just wondering is the POPUP_DELAY is too small, something is not ready?

So I try to increase the POPUP_DELAY, and then every thing ok, amazing.
But sorry to all, I don't know the reason. lol

I'd like to increase POPUP_DELAY, but failed to compile it from source.

has anyone found anyway?

Harsh, I love clipit, been using it for years, recently upgraded to 19.10 and now it's not working. :(

I've just noticed this, took me a while to work out why shortcut keys weren't doing anything in other applications but also did nothing in Ubuntu.

Is it possible to install an older working version? I tried to follow the instructions from @Darcidride but unfortunately I got an error trying to use the -t stretch parameter.

Yes, it is possible to use version 1.4.2-1.2 (works fine for me on Ubuntu 19.10)

@SuzanaK thanks, would you mind explaining how I might do so? Sorry I'm an Linux n00b!

@SuzanaK thanks, would you mind explaining how I might do so? Sorry I'm an Linux n00b!

I downloaded the .deb file from here and installed it (in Ubuntu you can install .deb files with right mouse click or in the terminal via sudo dpkg -i <xyz.deb>).

I would actually suggest using apt to install the deb file as it would take care of dependencies as well. In this case I guess it's a nonissue but for future references.

(just do sudo apt install ./my.deb)

The old version worked. Thanks!

Today I was informed by my upgrade procedure that clipit has been replaced with diodon.

I have tried to use it and didn't like it at all.

I guess it's a goodbye to those projects for me :shrug:

@stefanos82 I recently came across: https://extensions.gnome.org/extension/779/clipboard-indicator/. That has been working pretty well for me.

I decided to use the XFCE4 clipboard and it's quite easy to use.

It has its own history mechanism that you can use much like clipit.

All you need to do is to assign it to a hotkey shortcut and that would be it, really.

Do either of those allow for keeping clipboard and primary in sync ?

Do either of those allow for keeping clipboard and primary in sync ?

@mckellyln When you say primary, what exactly do you mean?

Can you explain it to me please as I'm not a native English speaker?

Many clipboard managers keep the primary and selection clipboard "in sync" at least as an option.
X11 has 2 clipboards (3 actually) and keyboard ctrl+c / ctrl+v ususally is connected to one clipboard and mouse drag+copy usually goes to another clipboard. If the clipboard manager keeps them in sync then you can drag+copy with mouse and ctrl+v with keyboard to get the same result.
I am just asking of there is an option such as "sync clipboards" you can select if you want.
"in sync" here means make them always the same, if one changes then copy it to the other so they match.

You mean this?

From Paste instantly you get three options: None, Ctrl+V, and Shift+Insert

I hope this helps.

I am not sure, it does not seem clear to me from the words above.
I was only trying to find out, as if it does not support this then I would keep looking for a clipbaord manager that does support it :-)

When I hovered over Sync mouse selections, I get the following message tooltip:

If checked, the selections will be synced with the default clipboard in a way that you can paste what you select

Does this help a bit more this time?

Yes, that does seem more like the same as keeping the clipboards in sync. Thanks!

This is fixed in 1.4.5.
I will sync missing patches from this version to my ppa and also build deb package.

Issue is not related to hotkeys - it is problem with GtkMenu.

@afelinczak
Your fix is working, but we lose the notification icon (topicon) feature, is it normal ?

On GDM 3.36.2 in my case

Hey,
It may be related to how deb package is compiled. Clipit compile scripts has flag enable-appindicator, switching it can help.

I may prepare second deb package, but for next 2-3 weeks Im very busy and cant promise any date.

Thank you for your quick answer

No problem, we will do as in for a few weeks

We're very grateful for your fix, keep your time :)

@Darcidride uploaded deb file with app indicator flag on.
Please let me know if this fix icon issue.

@afelinczak Still no icon in my side

I'm using this version of clipit from your personal repo (focal version)

clipit:
  Installed: 1.4.5+git20200624-1ppa1
  Candidate: 1.4.5+git20200624-1ppa1

Some more information if it can help :

gdm3 --version
GDM 3.36.3

But clipit is working great, I'm using it with shortcuts, just no gdm3 status icon

hey @Darcidride
Sorry for misunderstanding - I uploaded deb file here on github (release section) not to ppa.
I may get 2 versions to ppa but on daily basis I'm using Ubuntu Mate and current PPA version works ok for me.
Please check this one and let me know if icon works
https://github.com/CristianHenzel/ClipIt/releases/download/v1.4.5/clipit_1.4.5_amd64_indicator.deb

Hi @afelinczak
I installed the version linked from the GitHub link
The app indicator is there ! :+1:

I needed to force install since the semversioning is older than the other one I installed, and I apt-mark hold this package just in case

Well, everything is working perfectly in my side, thank you very much for your fix !

Did anyone have luck with the fixed package on Ubuntu 19.10? I tried both packages from the launchpad site and both posted on the github release page but no luck - I get a warning that the binding of the hotkeys failed and nothing else - no icon, no error message.

Im not sure if anyone tested on 19.10 @SuzanaK but from the error message I would check if any other app is not using same hotkeys as clipit.
I assume you are using deb file from third post above?

yes I used this deb file from above but also this deb file https://github.com/CristianHenzel/ClipIt/releases/download/v1.4.5/clipit_1.4.5_amd64.deb and both from the ppa. None of them worked, I also don't get an icon where I could change the hotkeys. According to the Keyboard Shortcuts, no other application is using e.g. Ctrl+Alt+H which I used for displaying the history. After installing and clicking on "Launch", nothing happens. When I start clipit in the terminal, I get the warning for the hotkeys and then nothing else.

Please verify all bindings are free:

History | Ctrl + Alt + h
Actions | Ctrl + Alt + a
Menu | Ctrl + Alt + p
Search | Ctrl + Alt + f
Offline mode | Ctrl + Alt + o

Yes, everyone of those is free. But I don' t think that's the problem - the whole app won't start but there's no error message.

Sorry, the failure to start had nothing to do with clipit, I had a problem with my display manager.
The package here https://github.com/CristianHenzel/ClipIt/releases/download/v1.4.5/clipit_1.4.5_amd64_indicator.deb works.
Sorry for the confusion and thank you!

@SuzanaK I tried to test this Today, but 19.10 has reached end of life and I was unable to install clipit as ubuntu repos are not active anymore.
I suggest upgrade to 20.04 LTS.

Maybe someone can add a comment on this project readme, under discontinued, to inform that we can use this package instead of moving to another tool

@Darcidride good idea, I have PR open related to meson, will add note to readme.

Same issue in my case (Debian testing)

Hi, same issue here :

The history pannel is like this, and the preferences panel is freezed after a first click inside it, also the hotkeys to access history clipboard doesn't work anymore...

Some logs :

System informations

uname -a :
Linux oab-cycd9w1 4.17.0-1-amd64 #1 SMP Debian 4.17.8-1 (2018-07-20) x86_64 GNU/Linux

cat /etc/debian_version : buster/sid

Temporary solution

Since i didn't see any news about a potential fix, I removed my clipit version and switch to the 1.4.2 version for the strethc repository.

If you also need this, here is the steps :

1. Check the different version you can install

$ apt-cache policy clipit
clipit:
  Installed: 1.4.2-1.2
  Candidate: 1.4.4-2
  Version table:
 *** 1.4.4-2 900
        900 http://http.debian.net/debian buster/main amd64 Packages
        -10 http://http.debian.net/debian unstable/main amd64 Packages
     1.4.2-1.2 100
        -20 http://httpredir.debian.org/debian stretch/main amd64 Packages
        100 /var/lib/dpkg/status

(in my case i'm on Debian testing, so i installed the 1.4.4-2 version of clipit from 'buster/testing' repository)

1. Then remove clipit (don't purge it, you will loose all your preferences)
   $ sudo apt autoremove clipit
2. Now install again clipit but from the repository you want, in my case 'stretch/stable' repository
   $ sudo apt install -t stretch clipit
3. Finally, check the installed version :

$ apt-cache policy clipit
clipit:
  Installed: 1.4.2-1.2
  Candidate: 1.4.4-2
  Version table:
     1.4.4-2 900
        900 http://http.debian.net/debian buster/main amd64 Packages
        -10 http://http.debian.net/debian unstable/main amd64 Packages
 *** 1.4.2-1.2 100
        -20 http://httpredir.debian.org/debian stretch/main amd64 Packages
        100 /var/lib/dpkg/status

Enjoy, you will now be able to launch again clipit without a freezed preference panel and with an hotkey working. (and everything else)

E: The value 'stretch' is invalid for APT::Default-Release as such a release is not available in the sources
