Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.5-3.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

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

Was copying a folder to another location on the same harddrive, plus it has crashed randomly since I installed the kde-desktop via Gnome 3.2

- Unusual behavior I noticed:

I'm running Fedora 16 with KDE and Gnome installed on an Acer Titanium laptop and I have two LCD screens connected, one via HDMI and the second one via VGA.

Yesterday, suddenly the screens went black with out any reason while I was only minimizing a window on the desktop. Since then I have had massive problems trying to get the desktop to show and work correctly properly using this setup.

- Custom settings of the application:

None perticular. Only what is mentioned here above.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
