Bug#883636: ShowQ doesn't start

[trebmuh at tuxfamily.org]

Package: showq
Version: 0.4.1+git20161215~dfsg0-2

Dear debian maintainers,

trying to launch showq (debian stretch here) doesn't work at all.
When ran from a terminal, it tells:
$ showq
ShowQ:out_1 # system:playback_1
ShowQ:out_2 # system:playback_2
ShowQ:out_3 # PulseAudio JACK Source:front-left
ShowQ:out_4 # PulseAudio JACK Source:front-right

Then a pop up windows appears telling:
> Show Q encountered an unknown error.
> Please report this error to the developers of the program.

Pushing the "OK" button, and it stops.

I've already reported this to upstream :

Cheers,
Olivier
