Application that crashed: amarok
Version of the application: 2.3.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
A while ago I set first level sort to Album, and second level to None. Just before the crash, I noticed that the actual sorting of my collection wasn't following the first and second level settings. While trying to work around that bug, I clicked on the Merged View button, and Amarok crashed.

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