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 2.6.31-19-generic-pae i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Amarok crashes on this action:
1) Type in characters in search box (magnatune)
2) press enter

I tested it with the other possible search options, such as Jamendo and Last FM and Amarok did not crash. I can reproduce the crash easily, as it happens consistently every time I do the above action.

Changes to system that possibly cause the problem:
1) changed some audio settings to fix the 'no sound in flash' bug.
2) changed the audio device order so that amarok tries to start using phonon (and always fails, reverts to HDA Intel (Realtek ALC883)) This change is related to the the bug mentioned in the line above.
