Application: kded4 ($Id$)
KDE Platform Version: 4.8.2 (4.8.2)

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

This crash happens sometimes when plugging in power adapter. 

Crash Reporting Assistant finds a few similar reports, but all of those are for older kde version  and marked closed as fixed.

The crash can be reproduced some of the time.

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