Bug 280874

Application: kontact (4.7.0 )
KDE Platform Version: 4.7.00 (4.7.0) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 3.0.3-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
While reading my RSS feeds in Akregator, it often occurs that the application crash when going to the full article in the web site. This occurs for example on Phoronix.com or on some blog post in Planet KDE.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
