[Pkg-mpd-maintainers] Bug#761347: mpd: Crash when enquing

[frozencemetery]

Package: mpd
Version: 0.18.13-1
Severity: important

Dear Maintainer,

When enqueueing a file to mpd, occasionally the following crash (captured in
gdb) will occur:

[Switching to Thread 0x7fffe2c3b700 (LWP 26272)]

My guess based on where the traceback goes is that this is the fault of libav,
though I have not troubleshot farther.

Thanks!
