Steffen,

it can be reproduced quite easily:
- just remove the pfcache.db (or move it aside) and
- surf to the url: 
https://<your-domain>/kolab/freebusy/<user>%40<your-domain>.ifb
if doing this the error mentioned above is reported....
So somewhere the code is not complete.  Marcus' patch prevents
the error.  Perhaps there are indeed are ways to prevent the error...
