Bug 275417

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.80 (4.7 Beta1) "release 6"
Qt Version: 4.7.3
Operating System: Linux 2.6.37.6-0.5-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

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

When changing the Desktop Layout (under Desktop Settings) to anything other than the default "Desktop", the plasma Desktop crashes.

The crash can be reproduced some of the time.

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