Application that crashed: akregator
Version of the application: 1.5.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.32-020632-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was reading this post:
http://www.phoronix.com/scan.php?page=news_item&px=NzkyOA
and press the "Comments & Discussion" button that links to comment pages.

While the page is loading I minimize the window and akregator suddenly crashes.

I cannot remember if it was fetching all the feeds.
I've around 50 feeds and all preferences (backends, times for fetching, ecc) are stick to their default values
