[Bug 986774] Re: infinite loop in mumble at/near exit (ran with pasuspender & alsa)

[Tuomas Heino]

Since pasuspender seems to handle manually sent SEGVs to mumble, there
does not seem to be a straightforward way to get apport-retrace of
this...

End of Backtrace.

TEST CASE:
- configure mumble to use alsa for sound input & output, text-to-speech off
- run "pasuspender mumble" and choose quit from the menu

Expected result: program quits and you get back to shell prompt.
Actual result: mumble gets in an infinite loop

Reproduced only with alsa, oss not tested. Does not occur when both
input & output are set to pulseaudio and mumble is ran without
pasuspender.

Additional notes:
- run "killall /usr/bin/speech-dispatcher" between repeated test runs to return to "pristine state"
- (another?) infinite loop also occurs if you try to change both input and output at same time back to pulseaudio, doing the change one at time avoids that infinite loop.
