[sync] Duplicated event on device after editing in kronolith

[Paolo Cravero]

Hello.
I've browsed all 2009 archives but did not find a similar request.

Client: Windows Mobile 6.1 and PPC2003
Funambol: latest 6.5.x and 6.0.x respectively
Horde Groupware Webmail Edition: latest release

An event existing on Horde, modified in Kronolith after the first sync (with 
device initialization) gets duplicated on the device if edited in Kronolith 
itself. Operations sequence:
- create events in kronolith
- first sync or recover (cleans device calendar)
- modify an existing event in kronolith
- sync again
=> event duplicated on device

The change can be the time or subject or description, doesn't matter.

I have a copy of both first sync and second sync debug files. The only 
relevant information I could spot in second sync log.txt is:

WARNING:Unable to create change for server id 
20090624100341.163376ghfdtc3bod at 172.22.21.131: client id not found in map, 
adding instead.

This is the ID of the event I modified, which exists on DB (MySQL).

We can replicate this behavior at each full sync server -> device. I even 
tried with a brand new horde account and just two events as a starting point.

Any debugging pointer?
Paolo
