Here in the traceback, the subscribe CGI is calling the list object's
AddMember method to add the member

Then within the AddMember method in
/usr/local/mailman/Mailman/MailList.py, the above line calls the
list's getScriptUrl method which triggers the exception below saying
the list object has no getScriptUrl method.

There are two things seriously wrong here:

1) In the 2.1.12 released MailList.py, there is no line containing the
name 'listinfo_url' anywhere in the module

2) the 'getScriptUrl' list method doesn't exist, thus the exception.
The method's name is 'GetScriptURL'.

So, the question here is where did this MailList.py module come from?
Is this a source install or a package? Did you modify it in any way?
It is clearly not an unmodified source distribution, and it is clearly
