Description Thomas Baag 2012-03-27 20:31:59 UTC 
Application: rekonq (0.8.0)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.3.0-rc6+ x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Using WebInspector (by right click menu -> inspect element) and closing the WebInspector panel afterwards. Rekonq also crashes when closing a tab if a WebInspector panel was created for this tab.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
