Description correo 2012-08-28 06:55:16 UTC

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

New crash information added by DrKonqi

dolphin (2.0) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1

- What I was doing when the application crashed:
1) Select a file in Dolphin
2) Use ALT+TAB in order change the application and do a drag and drop of the file in another application (here google chrome)
3) Hold on the ALT key drag the selected file and move de file
4) let the ALT key free (to go to select the application where to drop) and Dolphin crash.

- Unusual behavior I noticed:

- Custom settings of the application:
The environnement is under kde and 3d functionnality (cube, gelly windows, window explosion while quit ...)

Thanks for the bug report! Looks like a Qt issue which has been reported already.
