Merging with 116482. 

Likely means one of your feed got corrupted.

Workaround: I found that if you remove your Archive directory, Akregator will open as it should.  The Archive folder on my system (Kubuntu 9.10) is located here:  ~/.kde/share/apps/akregator/Archive  I assume that's the same place for most people.

It appears that the only thing lost by the removal is saved feed items.
