Bug 325691

Application: kded4 (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-31-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:

I booted my machine HP625 laptop. After login kded crashed

- Unusual behavior I noticed:

I'm using two displays but my settings were lost, both displays showed the same (wallpaper, panel, conky). In systemsettings only one display were shown HDMI-0, the laptop display LVDS was gone. This didn't happen when this bug occured the first time and I reported it.

The crash can be reproduced sometimes.

-- Backtrace:
