Bug 305511

Application: rekonq (0.9.1)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was attempting to start private browsing. The moment I clicked it rekonq crashed. I reopened rekonq, restored my session and attempted to private browse again. Once again rekonq instantly crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
