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 opened rekonq browsed a few pages then closed it. After closing it, I was surprised by this crash report. Identical problem has also occurred with VLC Media Player so I decided to report the crash.

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