Application: kded4 (4.11.1)
KDE Platform Version: 4.11.1
Qt Version: 4.8.4
Operating System: Linux 3.11.1-031101-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Happens on evry login and when i conect a HDMI cabel.
It sems kscren is responsible fore the chrash.
Since i use a dual monitor setup kdeinit chrashes evry time  i boot.

- Unusual behavior I noticed:
Icons in tray chane, spesificly kmix icon canges from the plasma theme one to default.
Suspend dont work any longer. i had to restart kdeinit4 whit hdmi unplugd to file this bug.

The crash can be reproduced every time.
