KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic i686
Distribution: Ubuntu 13.04

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

I clicked the like to petfinder.com from google search results when rekonq just crashed. Reopened and tried again and the same thing.

The crash can be reproduced every time.

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