This exact issue started happening to me this morning.

[Reported to Ninjas]

I believe my iPod and work versions were attempting to sync at the same time, but I've deleted my copy-in-progress .ofocus files and re-synced the work computer to no avail. I've turned off iPod syncing for now and will see what happens with the laptop when I get home.

Update: Laptop sync failed, too.
