Application: rekonq (0.9.1)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

I mainly use x11vnc to access my desktop, but after closing the connection and reconnecting from somewhere else I usually find rekonq has crashed. I usually have multiple tabs open, but from what I can tell most pages are not ad-heavy.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
