[kronolith] Can't see kolab shared calendar with kronolith

[s.truppe@email.amergy.com]

 I'm using kolab beta5 with the lastest horde framework with kronolith and imp. 
Imp works fine but i have troubles with kronolith. I allways got the error message:  

PHP Fatal error:  Call to a member function on a non-object in /kolab/lib/php/Horde/Kolab.php on line 552

I found the problem allready in the mailing list under: 
http://www.intevation.de/pipermail/kolab-devel/2005-January/002895.html

But when i uncomment these few funtions i can add events to the calendar, but i doesn't see
any event from my kolab calendar. 

Now i also get other error messages, a normal user gets this error:
Call to undefined function:  getrecurtype() in /kolab/var/kolab/www/horde/kronolith/lib/Driver/kolab.php on line 74

and the administrator this one:
Call to undefined function:  hasrecurtype() in /kolab/var/kolab/www/horde/kronolith/lib/Kronolith.php on line 394

I've tried to update horde and kronolith but nothing changes. The settings in the configuration files are all
correct, i also added a new user over the kolab interface so the calendar is recreated but kronolith does 
not show me any event from his calendar :(.

I have realy no idea what i've done wrong, i followed the instructions from the webclient doc and read all INSTALL's
and README's but no chance.

I hope that someone here does know a bit more about that,

with best regards,
