Application: kded4 ($Id$)
KDE Platform Version: 4.7.3 (4.7.3) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.1.0 x86_64
Distribution: "Gentoo Base System release 2.1"

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

I was trying to lock the screen with the shortcut (alt+ctrl+L) and it crashed. When I tried again it locked fine so I can't really reproduce it easily. There was nothing out of the ordinary opened on the desktop that could trigger that (at least not to my knowledge).

The crash can be reproduced some of the time.

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