[SyncEvolution] Error 412 but sync apparently successful

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I did a clean install of Ubuntu 12.04, replacing my earlier version upgraded from 11.10, and a few "interesting" things have happened with SyncEvolution as a result. The setup is a Nokia E63 syncing via bluetooth with Evolution, which is connected to a Radicale server (the recent version from Git). Initially, I set up the new Evolution profile incorrectly - wrong names for the tasks and the memos databases. The sync refused to finish and I had to cancel it. Once I'd discovered and fixed those errors, the sync would not propagate a new event from the PC. But when I deleted that event and then reinstated it, SyncEvolution complained about the missing event and generated a 412 error, and wouldn't complete the sync. The next trick was to restart both the phone and the PC. Now the sync runs successfully, which means that it propagates events in both directions, and actually completes, but I'm still getting the 412 error. What's the 412 error about, and how can I clear it? Thanks Jane Atkinson
