Bug 288784

Application: kded4 ($Id$)
KDE Platform Version: 4.7.90 (4.8 Beta2 (4.7.90) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 3.1.0-gentoo-r1 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
- What I was doing when the application crashed:
I've opened the "Configure Window Behaviour" dialog from kwin's context menu, when kded crashed.
I don't think that this is really related to kded's crash, but it was the only action I did at the moment it crashed. Couldn't reproduce it yet, but maybe the BT is enough to see what's wrong in kded's source.

The crash does not seem to be reproducible.

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