Bug 258362

Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.80 (4.6 Beta1)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-rc3-git1-7-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- Unusual behavior I noticed:

Plasma worked just fine after the upgrade to 4.6 beta1 but suddenly had crashed when I came back - and couldn't be restarted, crashing again and again... :(

I have as widgets mostly microblogs (2), a few clocks (as plasma is all about the clocks, right?), a photo widget, plasma NM, otherwise nothing special...

The crash can be reproduced some of the time.

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