Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.1
Operating System: Linux 2.6.35.11-83.fc14.x86_64 x86_64
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
- What I was doing when the application crashed:
*) I have 2 displays on this box and I am using xrandr to configure them.

1) I executed this command: "xrandr --output VGA1 --preferred --rotate normal --output DP1 --preferred --rotate left --right-of VGA1"

2) The desktop was reconfiguring itself.

3) I didn't wait untill the desktop finish the reorganization, and I executed this command:
"xrandr --output VGA1 --preferred --rotate normal --output DP1 --preferred --rotate normal --right-of VGA1"
(please note the rotation of output "DP1")

4) Plasma immediately crashed.


- Unusual behavior I noticed:
*) My DP1 screen was flickering, and usally executing those two commands solves the screen flickering
(flickering = 1 second of black screen, which repeat every 2~10 seconds)
