Bug 263574

Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

Nothing specific... using Firefox as the crash happened. This happened for the scond or even third time today.


- Unusual behavior I noticed:

A lot of other KDE applications also crashed at the same time: Plasma, Kopete, KMix, Amarok and Nepomuk (even twiece).

The crash can be reproduced some of the time.

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