Bug 319051

Application: kded4 ($Id$)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic x86_64
Distribution: Ubuntu 13.04

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

There are two possibilities to reproduce the BUG:

1st) Connect the display/monitor already before startup and boot. Finally there will be a KDE-Crash after the Login in Kubuntu and the display settings were resetted

2st) Connect the display/monitor if Kubuntu is already running. After detect the display KDE crashes and the crash report occur.

The crash can be reproduced every time.




Reproducible: Always
