Bug 214581

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 i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
In fact, Amarok crashes nearly every time it has to move files to the collection. After restarting it, the files all seem to be OK and in the right place.

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