[Merge] lp:~raj-abhilash1/mailman/bugfix into lp:mailman

[Barry Warsaw]

I'd like to merge this into trunk and create a release blocking bug for it.  Then when Falcon releases 0.3 in the next day or two, we can verify that it fixes this problem and block the MM3 release.

Can you resolve the conflict?
