well, that's expected. After manually deleting all config info, the next 
sync session does a slow sync:
all server data is sent to the client and vice verca. As there's 
currently no check for duplicates, this produces lots of duplicate entries.

Shouldn't be. There's been an issue with vcard2.1/3.0 versioning that 
should be fixed by now in cvs.
