Application: plasma-netbook (0.1)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-18-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
When suspending kwin's desktop effects, plasma-netbook crashes under some circumstances, this latest one being the top panel hiding and moving my mouse up to reveal it again. I experience no crashes if desktop effects are left on.

The crash can be reproduced some of the time.

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