Application: akregator (1.6.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-gcc44 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I have low-bandwidth Internet connection. I chose a feed which contained a big picture. It was rendered too slowly, so I clicked another feed in the list, and Akregator crashed.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Akregator (akregator), signal: Aborted
