Bug 275018

Application: kded4 ($Id$)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

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

Firefox was running although i wasn't physically using it.  The laptop was on battery power and running low, received a notification stating power getting low so proceeded to plug mains adaptor in.  As soon as mains adaptor was plugged in a window popped up stating the KDE Daemon had crashed.

-- Backtrace:
Application: KDE Dæmon (kdeinit4), signal: Segmentation fault
