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

I just turned on the pc. Then i connected the VGA cable to the monitor and i pressed on the automatic fit button (for join the two screens).
Hence the popup crash window appeared. I don't know if this is correlater or not, but surely i didn't see any problems on the video.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
