[SyncEvolution] issues with syncing photos

Hello, I'm having some issues with synchronizing photos. In my setup I'm using Funambol as a server, clients are Syncevolution and Funambol for android. The problem appears in the following case: 1. the "Test" contact has been modified on the android device (any field besides photo) 2. syncing with syncevolution gives a lot of lines with the same warning "[WARNING] libebook: invalid character found in parameter spec", but synchronization completed "successfully" and... photo's gone. I'd appreciate any thoughts regarding this problem. Regards, Vlad.
