Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Recently Amarok stops after every sond and I have to click play each time. Often during the play a notification appears, something about Phonon fallback. After that sometimes the Notification message and theAmarok OSD don't display the same song (Amarok is always correct). 

This time Amarok crashed seconds after the notification appeared. 

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
