Description dorian.gray88 2011-02-21 15:02:40 UTC
Application: kwin (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I was taking the mouse pointer to the top of the screen to activate the top custom button (i mean the custom button area at the top-left, top, top right, right and so on, in the screen)  to change the desktop.  
- Unusual behavior I noticed:
My bottom panel is normally hidden. When i put the mouse on the bottom to show it, in the center of the screen appear something like i had opened a folder (a folder window) but i can see only the edge. Obviously, when the panel disappear because i change the mouse position, this fake window disappear too. This behaviour is not continuative. It is random. But if this fake window appears one time, it appears until i turn off the computer.
I don't know if this behavior is related to the error, but it is strange

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
