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:
I have my collection on a ntfs drive. Clicking "repopulate" would crash Amarok every time. So I copied the collection to a ext4 partition (home) to rule out ntfs driver. It crashes less now but still does. This is a backtrace of a crash with collection on ext4.

 -- Backtrace:
