It is not possible to unsubscribe from bug 47046 (original bug) since one is subscribed only to its duplicate and is just "notified" about changes in the original one (it is not a proper subsription). To stop the e-mail flood one need to unsubsribe from the duplicate. See bug 48860 for more details.
