Description Gkok 2012-07-01 12:34:15 UTC 
Application: dolphin (2.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
* I started a drag-and-drop from Dophin
* then I realized the Thunderbird edit-email window was not visible enough
* during the dragging I used Alt-Tab to bring the Thunderbird edit-email window to the top
* then I dropped the file onto the attachments area of the Thunderbird edit-email window
* the Dolphin crashed
* a few seconds later Thunderbird also crashed

Note: Thunderbird was at version 13.0.1 (latest stable at the time of this writing.

The crash can be reproduced every time.

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