Bug 281382

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I started playing a Flash animation on www.spiegel.de browsing with Mozilla 6.0.1.

- Unusual behavior I noticed:
I experience frequent crashes of Plasma Desktop, after I wake my Compaq N620C Laptop from standby. Most of the time these are not 'complete' crashes, but I experience malformed behaviour: my laptop display is displaced downward and to the right. I get black bounds to the left and on top. Oddly enough I cant push the GUI buttons where they are displayed, but on there original locations.

The crash can be reproduced some of the time.

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