Version:            (using KDE 4.3.4)
OS:                Linux
Installed from:    Ubuntu Packages

Application that crashed: kded4
Version of the application: $Id: kded.cpp 1031638 2009-10-05 16:59:11Z lunakl $
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.6.0
Operating System: Linux 2.6.32-6-generic x86_64
Distribution: Ubuntu lucid (development branch)

What I was doing when the application crashed:
Crashes everytime  i start my KDE- Desktop. Crashing programs are kded4 and plasma-desktop. I still can use ALT+F2 to run programs but there is no taskbar (i think no plasma at all).

Happens on Kubuntu Lucid Lynx, all recent updates applied.

 -- Backtrace:
Application: KDE-Dienst (kdeinit4), signal: Segmentation fault
The current source language is "auto; currently c".
