RESUMEN

Esto puede no ser un error, sino algo que me salí con la mía en versiones anteriores, pero con Ansible 2.3 RC1 si estoy verificando si una variable registrada por un módulo (con una cláusula when) está definida y luego obtengo un valor de sub dictado falla en 2.3 mientras que en 2.2 y por debajo funciona bien. Esto sucede específicamente cuando el módulo que registra la variable se omite por cualquier motivo y luego una tarea posterior verifica si la variable está definida y luego obtiene la subclave.
