[nag] Sync issues with nag/tasks

[Christian Luetgens]

Hi all,

after upgrading from Horde 4 to Horde 5, I have some issues  
synchronizing tasks with SyncML / Active Sync.

- SyncML: New tasks created in Lightning do not appear in Nag after  
synchronization. Funambol seems to be sending new tasks to the server  
alright, but they are not stored. However, changes to existing tasks  
are being uploaded to the server OK. Deletion sometimes works,  
sometimes not.

- ActiveSync: Same as SyncML, but what is worse: on every sync, all  
tasks are being duplicated - every time. In the duplicates, the  
description is filled up with garbage.

What could be the problem this time?
