Details

If two clients both enter generateNewSymmetricKeys, but don't race directly, both will upload and download their own keys, and will proceed with their sync. The first client's uploaded records will be encrypted with keys that were immediately replaced. The fix is to use X-If-Unmodified-Since to ensure that the upload is a compare-and-set. This used to be impossible, but Bug 693893 has now been fixed.
