Version:           unspecified (using KDE 4.5.0) 
OS:                Linux

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
This only happens sometimes, I can reproduce it by adding and removing default panels. Sometimes it crashes when adding and sometimes when removing. I tried 10 times with adding and removing an Empty panel and it never crashed, this may be pure chance or related to the problem.

This is version 4.5.0 installled from http://download.opensuse.org/repositories/KDE:/Distro:/Factory/openSUSE_11.3/

The rpm is kdebase4-workspace-4.5.0-493.3.i586.

I am running OpenSUSE 11.3.

The crash can be reproduced some of the time.
