Akonadi blocks kaddressbook

Hi,

I’m running OpenSuse 11.2 with KDE 4.4.1. I have a serious problem: Akonadi blocks my kaddressbook. It just shows a grey screen with the message “Akonadi doesn’t work correctly”. When clicking on “details”, I get a list of problems which I do not know how to solve:

Akonadi Server Self-Test Report

I’m sorry if this has been discussed here before, just give me a pointer. The search didn’t help me.
From that grey screen I cannot access any of my addresses.
