Application: rekonq (1.1)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
It was a simple session on a very simple web page( http://thor.info.uaic.ro/~orar/participanti/orar_I3A2.html ).
On close it crashed. Wasn't able to reproduce.
I hope the backtrace can help find the problem.

- Custom settings of the application:
Under webkit tab I activated(these ones were deactivated):
- WebGL
- Offiline storage database
- Offline web application cache
- Local Storage

The crash does not seem to be reproducible.

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