Bug 255669

Application: rekonq (0.6.1)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
case 1: trying to use the facebook-chat
case 2: watching a video on youtube (youtube generally doesn't work well with rekonq as videos 	often only appear after refreshing the site, while the sound works perfectly well right away)
while using rekonq, i also had kopete and the dragon player running

The crash can be reproduced some of the time.

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