problems with kaddressbook and egroupware

Hello,

I'm using eGroupware (1.0.0.007) on my Debian-server (sarge) for
managing contacts and calendars. So far, the web-frontend works fine.
Korganizer also works fine, it shows me all events I made in the
web-frontend and I'm able to create new ones, too.

Now I want kaddressbook (3.3.2) to use the data from eGroupware.
I can create new contacts. They also appear in the web-frontend.
But unfortunately I can't see any contacts in kaddressbook at all.
The list is completely empty.
If I start kaddressbook from konsole, I can see my first contact in
something like XML in the console. So I think that the communication
between kaddressbook and eGroupware is working. (I can create contacts,
too.)
Any hints how to get my eGroupware contacts into kaddressbook?

You can see the whole output of kaddressbook at

PS.: My English isn't very good as I'm from Germany, but I hope you can
understand my problem :-)
