KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)

-- Information about the crash:
An RSS feed has this link in it:
http://thenextweb.com/industry/2011/05/18/not-so-fast-sonys-playstation-network-hacked-again/

When I click to open the link in a new tab, the web page starts to show, but Akregator crashes before it is displayed completely.

If you cannot reproduce this, I could compile Akregator or whatever you like with debug information to generate a better backtrace.

The crash can be reproduced every time.
