Bug 213439

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:
After deletion of ~/.kde/share/apps/amarok Amarok starts fine.
When amarok starts to scan my whole collection it crashes.

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