Bug 228099

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 i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
When entering a search string for the Jamendo db, ie "Bach", Amarok crashes after second or third character. This is reproducible at will.

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