Qt Version: 4.6.2
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
I was navigating through the list that displays RSS feeds and kontact crashed. I don't know if at the same time it was fetching new emails or not, but it is possible because I set a timer of 10 minutes to do this. Also, I am not sure if it crashed when I clicked on a table item or someplace else, but I am >90% sure i tried to click a feed category.

 -- Backtrace:
Application: Kontact (kontact), signal: Aborted
