Description Eike Petersen 2011-08-08 11:09:04 UTC

Application: rekonq (0.7.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

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

reconq was started by clicking on a link in another application (tagesschau.de, nothing fancy and no special popups or such things). Since I didn't want to use rekonq, I immediately hit the close button before the page was fully loaded. Then, the crash appeared.

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

rekonq (0.7.57) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.2

- What I was doing when the application crashed:

Exactly the same behaviour as the original reporter wrote - Rekonq crashed when i closed it (the page wasn't completly opened).

rekonq (0.8.0) on KDE Platform 4.7.3 (4.7.3) using Qt 4.7.4

- What I was doing when the application crashed:

I have loaded avi-file by Kopete.  I have clicked on link in the information window and reconq has been opened, but I have closed it before it opened the avi-file. So it crashed reconq.
