Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1) "release 390"
Qt Version: 4.7.2
Operating System: Linux 2.6.37.1-1.2-desktop x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I was browsing the Magnatune collection in Amarok when Amarok crashed. This is a known issue (bug 233170) and unfortunately it happens very often. However, this time Plasma crashed as well: I saw the panel disappear and then the crash handler popped up. Plasma crashing is not common on my machine.

I'm using openSUSE 11.4 and KDE 4.6.1 from the KDE_4.6 repository from openSUSE itself (not the default KDE for 11.4 though).

It's possible this is a duplicate, but there were over 20 possible duplicates shown and I didn't have time to compare all those stack traces. I hope one of the developers has the commonly reported bugs in his/her memory and can much more quickly determine whether this is a duplicate or not.

The crash can be reproduced some of the time.
