Application: kontact (4.7.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Linux Mint 12 Lisa

-- Information about the crash:
- What I was doing when the application crashed:

I was browsing thru the RSS feeds in the Akregator component of Kontact, and opened a link to be greeted by a crash. ( I was reading the Cyanide and Happiness webcomic to be more specific )
The page had loaded mostly, except for the adverts, so I've a hunch that it might have been the flash plugin.

The crash can be reproduced some of the time.

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