Bug 268493

Application: akregator (1.6.6)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-5-generic x86_64
Distribution: Ubuntu Natty (development branch)

-- Information about the crash:
- What I was doing when the application crashed: Launching akregator

The app crashes everytime I start it up.

I have managed to duplicate the problem by copying the data files in /.kde/share/apps/akregator to another computer. It seems that the files have somehow been corrupted by the app, even though I had shut the app down cleanly before the problem surfaced.

https://bugs.launchpad.net/ubuntu/+source/kdepim/+bug/734960

- Custom settings of the application: Check feeds upon startup.

The crash can be reproduced every time.

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