Bug 305309

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-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Whenever I close Rekonq with a webpage that contains an Flash plugin option the webpage crashes. If I close all tabs that contain the flash plugin the program closes normally.
The crash is dependant on the embedded flash, because if I view the same website with a flash plugin it crashes, usually a commercial, if this flash is not on the website, it closes normally. 

- Custom settings of the application:
I have set the flash plugin such that it will always prompt to load.

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