[nzlug] Problem with nzlug list - duplicate msgs

[Vik Olliver]

I'm getting every message twice. If I go to my mailman options to see
what's going on, I get:

Bug in Mailman version 2.1.5
We're sorry, we hit a bug!
Please inform the webmaster for this site of this problem. Printing of
traceback and other system information has been explicitly inhibited,
but the webmaster can find this information in the Mailman error logs.

Wasn't sure who to tell...

Vik :v)
