Comment 7 for bug 778437

It looks like this test changed during <http://bazaar.launchpad.net/~launchpad-pqm/launchpad/devel/revision/11566> done for <https://bugs.launchpad.net/launchpad/+bug/506256> when it changed from asserting that mail was sent once to asserting it is not sent at all. I guess the mail is now actually sent through some other path but I can't work out what that is.
