[Mailman-Users] cgi-bin/archives is confused with null params

[WATANABE Katsuhiro]

Almost all web site running mailman has a tiny bug in parameter
handling in $prefix/cgi-bin/archives.

If you knock http://any.site/mailman/archives (or our flagship
http://mail.python.org/mailman/archives for an instance),
you will get: 
    Bug in Mailman version x.yy.zz...
    We're sorry, we hit a bug!
    Please inform the webmaster...
Although the problem has no real harm and fix will come trivially,
I've enjoyed the universality and breadth of the symptom for a while.
