Comment (by dd32):

 Haven't tested, but this will be caused by our fix-the-revision-authors
 upgrade script, and the results above back that up.

 Basically, checking DOING_AUTOSAVE is not enough, as save_post is
 triggered during the upgrade for posts with revisions (a new post has no
 revisions and thus, doesn't trigger this).
 Plugins which include a nonce, and verify that as well when
 saving/updating the meta, won't trigger it since the nonce won't exist on
 the upgrade routine call.
