[Bug 507204] [NEW] OpenShot freezes/hangs on startup if jack is running

 

Public bug reported:

I started OpenShot, within a few seconds the window became grey and the
application would not respond.  I tried a couple of times and then
realised jack was still running.  I stopped jack and restarted OpenShot,
the application started again without freezing.

Looking into this, it turns out that jack suspends PulseAudio whilst it
is running.  I discovered that this could be reproduced by running
pasuspender.

Here is the test:-
1. Start OpenShot
2. Run "pasuspender -- xterm"
3. Wait for up to 30 seconds, the OpenShot window will turn grey
4. In the xterm window type "exit", OpenShot becomes responsive again

It is good to see that OpenShot resumes working again when pulseaudio is
resumed.  If we can find a way of handling the situation the user could
be notified.
