Bug 233189

Application: rekonq (0.4.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-18-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
When opening www.facebook.com, after typing in my credentials, the start page starts to load.
Before the page has been loaded completely (but parts of it have appeared), rekonq crashes.
This is reproducable.

I realize that there is a similar bug report (#226896), but that report claims the problem is solved in KDE 4.4.1. I'm on KDE 4.4.2 (using distribution Kubuntu 10.04 beta 1), and the problem persists (if it is the same problem - I'm not sure).


 -- Backtrace:
