Summary: Unsubscribe fails with buffer exception

Initial Comment:
A user subscribed themselves with a trailing space (%00), 
and now all efforts to unsubscribe the user fail:

>From the web interface, you can select the user and 
"unsubscribe" them, but they remain on the list (mailman 
returns no confirmation message)

With the remove_members utility, it tells me "No such 
member", even though find_members "finds" the member.  
I've munged the address every way possible (using python 
and shell regexps, adding Unicode, etc) and still can't get the 
member to unsubscribe.

I googled for an answer to this problem, and this seems to 
be the only solution:

http://www.mail-archive.com/mailman-users@python.org/
msg21153.html

I'd say since the solution requires editing a binary, this 
qualifies as a bug.

I've also searched the bug archive and couldn't really come 
up with an answer; I do realize that my searches might not 
have been correct, so if the answer is in the bug database, I 
apologize.

Thank you very much,
Fred
