Bug 299781

Application: rekonq (0.9.1)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to submit a form. Since it didn't seem to work, I tried to quit Rekonq (to restart it). Quitting the app result in crashing.

The crash can be reproduced some of the time.

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