Application: amarok (2.2.2)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-19-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I upgraded to Amarok 2.2.2 which worked fine except for MP3 support.  I found this thread http://forum.kde.org/viewtopic.php?f=115&t=83867&p=142480&hilit=mp3+ubuntu#p142480
to install MP3 support.  I installed libxine1-ffmpeg and started getting the crashes after that.

I have removed Pulse Audio from my system as it was not working with my sound card.

I am using Ubuntu 9.10 64-bit AMD.

The crash can be reproduced every time.
