Application: amarok (2.3.2)
KDE Platform Version: 4.5.5 (KDE 4.5.5) "release 1"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.7-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
This _could_ be related with bug number 254244, but I am not sure. The first lines of the backtrace look different, but I am not able to overview possible relations...
Okay, this is what happened:
I started Amarok after it already crashed, and I simply started listening to the first song, but then skipped this and the next two songs. Immediately (like microseconds later) Amarok just crashed again. I don't know what more to tell, it's a simple chain of harmless actions from my side...

By the way, on my machine, Amarok crashes quite often. Once or twice during 3-4 hours of listening to music would be an adequate guess. The kind of bug is always the same, I guess, as it always happens right at the beginning of one song. Before the first sound is audible. 

If you have further questions, please contact me!
Best regards,
Thomas

The crash can be reproduced some of the time.
