Version:           SVN (using Devel) 
OS:                Linux

Info from DrKonqi:

Application: kded4 ($Id: kded.cpp 1156841 2010-07-29 19:59:05Z zander $)
KDE Platform Version: 4.5.00 (KDE 4.5.0) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.35.2 i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I think this is related to bluedevil. Happend third time after I was using bluetooth device with bluedevil. After a reboot KDE Deamon crashed (it crashed once with bluedevil right after login) as in the title. Also — one time after such crash I lost all my plasmoids and wallpaper — had to set them again.

Seems that it happend few days ago and the problem won't go away (currently at revision 1166141).

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Aborted
