The Nag_Driver_Kolab breaks the Kolab format specification concerning  
the parent parameter.

The parent id of a task object should be stored as a UID hash when  
viewing the kolab.xml attachment of the Kolab storage object (i.e., a  
mail with one .xml file as attachment).

However, I see the UID hash stored base64 encoded:

"""

"""

The challenge now is:

   * storing parent ids as non-base64 encoded hash (7-bit encoding, sort of)
   * recognize parent ids that have been stored with base64 encoding,  
decode them properly
   * store base64-encoded parent ids as non-base64-encoded UID hash  
with next save operation

I am working on a patch...
