Description iskren 2013-01-03 08:35:48 UTC 
Application: rekonq (1.3)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic i686
Distribution: Ubuntu 12.10

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

When I close reqonq an error message the crash report wizard is instantly showing up. I'm running  Kubuntu 12.10. It seems to be occuring sporadically, I was not able to reproduce it the second time I tried, but it has happened before. Similar reports were either marked duplicate or resolved, hence filinga new one.

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