Application: kwin (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-26-generic x86_64
Distribution: Linux Mint 15 Olivia

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

I inserted an SD card and selected view files in dolphin.
At that point the desktop became unresponsive. I was able to alt-tab between windows, but not use the mouse. After closing an application the desktop was not displayed (e.g. window remained displayed as if it was still open).

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