Installed from:    Debian testing/unstable Packages

I decided to try akregator as new feed reader. I downloaded all default feeds, read them a deleted all articles. After a while i clicked on task bar on akregator icon a clicked download all. There were two new. I wanted to read them, but akregator suddenly crashes with the following message (SIGABRT).

$ akregator -v
Qt: 4.4.1
KDE: 4.1.1 (KDE 4.1.1)
Akregator: 1.3.1

Application: Akregator (akregator), signal SIGABRT
