Everytime I try to sync with iSync, the sync fails on a specific contact saying it's JPEG file is corrupted. I can't figure out which contact it is. It also causes the CalDav account not to be set up in iCal as well because the whole sync just quits when it hits an error. Here's the output in Console.app:
