Package: libavcodec57
Version: 7:3.1.1-2
Severity: grave
I ran Debian testing on my desktop. Since about a day ago, pidgin
started crashing unexpectedly. After a little bit of debugging, I found
that it reproducibly crashes when trying to play sounds. Going a step
further, I made the test case as simple as:
$ gst-launch-1.0 filesrc location=/usr/share/sounds/purple/alert.wav !
wavparse ! audioconvert ! fakesink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Aborted (core dumped)
My dpkg.log has a bunch of ffmpeg-related package upgrades, including
libavcodec57, being installed on 2016-07-18, approximately when those
crashes started. Because of this and the backtrace below, I'm filing
this against libavcodec57 -- feel free to reassign if that's wrong.
The backtrace seems to be:

Finally, note that running "mpv /usr/share/sounds/purple/receive.wav"
seems to work without crashing (and produces sound), however, there is a
big yellow warning at the top that reads: "Warning: mpv was compiled
against a different version of ffmpeg than the shared library it is
linked against. This is most likely a broken build and misbehavior and
crashes are to be expected."
Thanks,
