According to the stack trace, you were changing the audio output device...

Note that VLC cannot crash PulseAudio. If PulseAudio crashes,p ossibly as a consequence of some VLC misbheaviour, then it is also a PulseAudio bug.

summary: - vlc crashed with SIGSEGV in __module_unneed()
+ aout_FindAndRestart() crashes VLC PulseAudio output
