Bug 303038

Application: rekonq (0.9.1)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: bezártam a rekong alkalmazást. Majd egyszerűen leáfagyott a rekong.

The crash can be reproduced some of the time.

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