Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0) "release 6" (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.5-default i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I selected the "switch back to Application Launcher Style" button, immediately after boot w/ no other applications open. 
- Custom settings of the application:
The computer which openSUSE is installed on is an ancient compaq nc4010. The only custom settings (other than the initial switch to the current launcher) is the switch of the windows decoration, which should have no effect. Everything else remains as installed.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
