Actually, I think I can see it anyway. simple_object_start_read returns
that when it doesn't recognize the object format. We should just return
without claiming the file in that case. It can be distinguished by getting a
NULL return and an errmsg from the call to simple_object_start_read(), but the
err value being zero.
