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

Inside a RSS feed reading, while on the web page i am trying to go to a new sub web page (same site). after clicking inside the web page Kontact dumps to the bug report.
Kontact was not doing this before today.
Although i have added three email accounts to Kontact Mail, also i did just mark all feeds as read. but have tried two times with same results.

The crash can be reproduced every time.

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