[Mailman-Users] list_members traceback error with ASCII character

[NOW Website Coordinator]

I also am having a problem with list_members in 2.1.1.  I got the following 
traceback when I use list_members -f :


Traceback (most recent call last):
   File "/usr/local/mailman/bin/list_members", line 232, in ?
     main()
   File "/usr/local/mailman/bin/list_members", line 207, in main
     s = formataddr((name, addr)).encode(enc, 'replace')
UnicodeError: ASCII decoding error: ordinal not in range(128)

It works if I don't use the "-f" option, but I need that option.

I found a previous person having this problem as well, but not really a 
solution:

check_db does not report any errors on this list.

Ideas?
