Bug 287607

Application: rekonq (0.8.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I just tried to run rekonq and it failed. Yesterday it worked fine. Maybe it's related to cache or wrong settings, I'm not sure...

The crash can be reproduced every time.

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