Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.1
Operating System: Linux 2.6.35.11-83.fc14.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I was adding and resizing Network, CPU and RAM widgets to the desktop. First the RAM widget refused to pop up the resize/config-menu while hovering mouse over it, after that the whole plasma crashed.

The crash can be reproduced some of the time.

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