[kronolith] Problem with Kronolith/Kolab

[Joscha Schmiedt]

Hello,

I have a problem connecting Horde3/Kronolith to my Kolab groupware. When
I try to make a new calendar entry, the page just reloads and Horde
prints three times: 

'Horde/Kolab: Successfully synchronised calendar "Calendar"'

On the Kolab Server:
/kolab/var/imapd/log/misc.log

The address book Turba2 is working though. I'm running Kronolith 2.0.3
and Horde 3.0.4 on a Debian System.

Any ideas? Thanks in advance.
