No group comment notifications

I've installed fbuntu on my netbook which runs Ubuntu 10.04.
from the first day on, I was not able to see group comments in my Messaging Menu (I'm not sure if i get any notifications from facebook, I am only sure that I get notifications from incoming messages)

The debug.log says:
