Bug 250982

Application: rekonq (0.5.80)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-20-generic x86_64
Distribution: Ubuntu maverick (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I visit a random page which has an embedded flash object
- Custom settings of the application:
I was trying lightspark from http://launchpad.net/~sssup/+archive/sssup-ppa instead of using adobe's flash plugin

The crash can be reproduced every time.

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