Update Kolab 3.2 on CentOS with errors

[Kolab, User]

Hi folks,

i have got kolab 3.2 up and running. everything works like a charm.
After updating packages via yum update i have got several problems:

- no synchronisation of calendars, contacts and tasks via activesync if 
they are stored within subfolders. (there are no problems of syncing 
data in main folders).

All folders are marked for synchronisation. This is really painful. Any 
idea?

thanks for a hand.
