-- Information about the crash:
Certain feeds (most of which contain images or embedded video) cause a sudden lockup and crash while navigating them. I can't be more specific because it occurs variably on several feeds - everything from BoingBoing to Reddit (which are configured for feed preview and "load website," respectively).

The crash can be reproduced some of the time.

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