The Problem is in turba/lib/Driver.php.
Patch attached.
Please also have a look at Ticket #11124 ...

and here is the addressbook (only one entry)

ok
started from scratch, sync log attached

This indicates there was error previously in the log. Either the data 
sent was corrupt, or the device did not receive it/like it.  Would 
need to see the complete sync session to know for sure.

No data for the contact is even being sent to the device, so the error 
(at least this portion of it) does not lie with ActiveSync. I would 
check Horde log and/or server error log for any other hints.

when adding a new contact (in Horde5) the new entry is created on the 
phone, but completely empty.
(teh contact has at least email and phone)
debug log attached.
