Application: dolphin (2.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- I selected a few files, then I used Alt+Tab to switch window so that I could drop them in a particular application. Just as the window started switching, Dolphin crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
