Bug 287937

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 2.6.37.6-0.9-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I observed this crash hundreds times, each time there was no clear explicit action done right before the crash. It appears as if something in the background causes the crash. 
In about 60-70% of the cases the crash is an endless one. That means that the crash handler pops up in an endless loop, it becomes hard to close them faster than they popup.

The crash can be reproduced some of the time.

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