Strange bug while syncing contacts (iPhone/kolab-syncroton 2.1)

Good evening together,

i've got a strange bug while syncronising contacts between 
kolab-syncroton and an iPhone4 with ios 6.1.
Whenever i get more than 25 contacts the iPhone syncs endlessly.

kolab-syncroton log:

----------------------------------------------------------

It seems like the contacts are always marked as modified and therefore 
they are synced, at least correct, over and over again.
