DB Error: not found with Horde and Kolab

[Florian Oszwald]

Hi all,

I now have horde installed working together with kolab on opensuse 10.2.

The problem is, that i get the message DB Error: not found everytime I log in 
on a new day or making a new entry in the calendar or in notes.

In /var/log/horde/horde.log I do not get any useful information about this 
problem. On the internet I found, that it might be related to the SQL, but I 
am using it together with Kolab, so there is no need for sql, is there?

Thank you very much in advance.
Regards,
Florian
