Description Guido Winkelmann 2013-09-08 21:57:02 UTC 
Application: juk (3.9.1)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0 x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
Juk will crash every time it stops playing a track, be it because it has reached the end of the track, or because the user presses the stop or forward button.

The Phonon backend in use is GStreamer, compiled against ffmpeg.

The crash can be reproduced every time.

-- Backtrace:
Application: JuK (juk), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

This is not a problem in the phonon backend but in Alsa, please report this upstream.

I do not have sufficient insight on what parts of alsa exactly are producing this problem to be able to report this upstream.
