[Mailman-Users] add_members and email confirmation

[Ren Bucholz]

This is a followup to an older message, but I wanted to say that Mark's 
fix worked for the error handling.  Thanks, Mark!

I'm still having a problem with the confirmations, however.  To recap, 
I'm trying to use a modified version of add_members (call it 
new_add_members) in order to subscribe people via my own webform (where 
PHP executes add_members).  I modified it because I'd like the list to 
be confirmed opt-in, but add_members assumes that the user has 
confirmed their subscription and doesn't bother with the confirmation 
message. There's a longer description of what I did in this list's 
archives, if you're interested:
   http://www.mail-archive.com/mailman-users@python.org/msg35077.html

The problem is that this script totally breaks Mailman's web 
subscription features.  The first time I run new_add_members, I get a 
seemingly normal looking confirmation.  Upon clicking the confirmation 
link, I get the Mailman's generic "Sorry, We Hit A Bug!" message.  And 
from that point forward, attempting to subscribe via the list's 
standard Mailman info page (foo.com/mailman/listinfo/your_list) 
generates the same error.  You can still subscribe by calling the 
unmodified add_members.  The error logs say:

If anyone has any idea how to fix this, I'd be most appreciative.  I 
should also mention that error isn't limited to a single address - 
subscribing me at fake.com via new_add_members will cause a web 
subscription for you at fake.com to fail. Thanks for reading this far!
