Application: amarok (2.5-GIT)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.3.6-zen-01698-g340405a x86_64

-- Information about the crash:
- What I was doing when the application crashed:

Playing several audio files in a playlist.

- Unusual behavior I noticed:

This behavior was only seen to happen with Ogg Vorbis or Flac files, while mp3 files had no such issues. Some Flac files would trigger a crash when they ended (which ones triggered this was not entirely reliable, but some were far more likely than others), and at least one Vorbis file would pause at 2 seconds and crash if I attempted to play it further (either by skipping further using the scrub bar or toggling between pause and play) with total reliability.

This backtrace is from one of the Flac files, and is consistent across multiple crashes . The Vorbis issue may actually be different, as I *can't* generate a reliable backtrace from it. Instead, I have repeatedly gotten backtraces with nothing other than the message that it was aborted. Since the Flac issue is causing a SEGV rather than an ABRT, they may be different manifestations of the same root cause (which I suspect due to how their onsets coincided), or may be entirely separate.

- Custom settings of the application:

This seemed to start after an update to Qt 4.8. Qt was built from the 4.8 branch's Git HEAD, and is revision a3d7244e99d230f4d3bc43c721257eef1ed333de.

Amarok is git HEAD of the master branch, revision 54cdbf0167250a25644b8514bac14911d0cd9407

(As a side note, please consider including the Amarok git revision in your automatically-reported version when building from Git. That way it gets included whether the user remembers or not. 'git describe HEAD' is a nice, simple way to do this.)

The reason I'm reporting this as an Amarok bug rather than Phonon-GStreamer or Qt is that no other software seems able to trigger it - looping some of the problematic tracks in JuK works without issue, despite using pretty much the same stack.

In the backtrace, thread 5 is likely the relevant one.

The crash can be reproduced every time.
