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 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I changed the third level to "none"
and then Amarok crashes, if I press "Toggle unfied view mode"
It is reproducible!

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
The current source language is "auto; currently c".
