[SyncEvolution] syncevolution - duplicate items

Refering to the prevous mail 'Missing close function': situation: debian squezze with syncevlution 1.1 running as server problem: after stopping syncronization from mobile (but this may happen just because of of connection loss), the next syncronization will duplicate ... triplacate and then quadruplicate contacts in addressbook. I'm using nokia N73 to test. Please, focus on that issue because it affects also other syncML servers like funambol. It would be great to have it working fine on syncevolution. I attached the log. Ask for any other detail you may need.
