Bug 227808

Application: akregator (1.6.0)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
Akregator is idling in background. A t some point it starts to fetch feeds and crashes. It fetches feeds every 30 minutes, but crashes once/twice daily. I have hundreds of feeds, so I can't easily tell which is the "bad" one.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
