Celery: Erro "Recebido 0x01 enquanto esperava 0xce" ao usar python-amqp

No Arch Linux com estes pacotes:

python-celery 3.1.11-1
python-kombu 3.0.16-2
python-billiard 3.3.0.17-1
python-amqp 1.4.5-1
rabbitmq 3.3.1-1

O erro abaixo é produzido. Eu li que mudar de python-amqp para librabbitmq-c corrigirá o erro, mas estou usando Python 3 e não há librabbitmq-c compatível com Python 3 disponível.
