[Mailman-Users] admindb: 500 error

[Zebee Johnstone]

Suddenly - as in it has been working fine, but some time in the last week
it has failed - the admin interface of all my lists is giving a 500 error.

listinfo is fine, mail is flowing freely.

Mailman version 2.05
httpd log: 
[Tue Oct  5 12:04:47 2004] [error] [client 218.214.72.52] Premature end of script headers: /home/mailman/cgi-bin/admin

That;s the only log line.

Nothing in any other logs that I can see.

I don't recall installing any software since the last time I know it worked.

If I try  running /home/mailman/cgi-bin/admin as root, I get a GID error,
if I run it as nobody (the apache user) I get HTML.  If I connect to
that as a URL http://my.machine.com/mailman/admin  I get the same HTML.

But if I connect to the admin database for a list
http://my.machine.com/mailman/admin/listname I get

I see in the archives several people have had this problem, but no one has posted
an answer.  If someone gives me one, I promise to post it for googlers the world
over...
