Wed Apr 10 00:28:10 UTC 2013 

You have been subscribed to a public bug:

I have updated to
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=13.04
DISTRIB_CODENAME=raring
DISTRIB_DESCRIPTION="Ubuntu Raring Ringtail (development branch)"

and now i get errors from time to time. It just happened while working
and currently i did not notice any problems during that time.

Due to a not running kded i can not use the report bug functionality.

Here is the backtrace:

Application: KDE-Dienst (kdeinit4), signal: Segmentation fault
