Hmm, from a quick google it appears you are not the only one who has seen this symptom with mount.ceph. Our mtab code appears to have diverged a bit from the upstream util-linux repo, so it seems entirely possible we have a bug in ours somewhere. I've opened http://tracker.ceph.com/issues/10351 to track it.
