Bug 225551

Application that crashed: amarok
Version of the application: 2.2.2
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I can reproduce the crash following these steps:
- starting amarok
- selecting Internet - Jamendo
- selecting a title or album
- droping to the playlist
- press the play button
After that it last a few seconds to crash amarok.
I have a 64-bit kubuntu karmic system on an i5-750 with 4 GB Ram, ASUS P7P55D-Board with onboard HDA Intel Sound. Thx a lot. Andreas.
