New crash information added by DrKonqi

akregator (4.7.0 ) on KDE Platform 4.7.00 (4.7.0) "release 6" using Qt 4.7.3

Akregator crashes when quickly selecting new (and propably uncached) articles. It happens when one selects an other article while the preview of the current one is still loading. The error is reproducible.

akregator (1.6.6) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

Selecting articles. I then tried to right click to delete them and Akregator promptly decided it didn't like to work any more.
