It seems to me that the logic in this change is not correct:

https://bazaar.launchpad.net/~mailman-coders/mailman/2.1/revision/1881

For lists with private_roster > 0, when the user has entered a email address 
which is not subscribed to that list, the return is taken without having 
printed a response.  In my environment, Apache httpd then sends a 500 Internal 
Server Error to the browser.  While not saying so in so many words, this 
behaviour does subtly disclose that the email address is not subscribed.  The 
only privacy-preserving way to proceed would be for Mailman to pretend that the 
user is subscribed, which is what happened prior to this revision.
