Bug 225612

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:
That's about it. I was in my Unknowns folder, and had an idea about the artist for one track. Tried to play it by right-clicking, and then Amarok crashed.

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