That is not the answer to the question I asked. I know you get the error
on an archive search. What I am asking is do you get the same group
mismatch error when visiting other Mailman CGI URLs such as
http://mymailman.com/mailman/listinfo/testlist or

This is because all the wrappers in /usr/local/mailman/cgi-bin/ must be
in Mailman's group and SETGID. I.e. the original group and permissions
were correct, the changed ones are wrong. This is not the cause of your
group mismatch error.

Mailman 2.1.19rc3 is fairly stable. 2.1.19 final will be released within
a week. See <http://www.list.org/>.

Note that you are using Richard Barrett's archive search patches. There
is a set of these for Mailman 2.1.18-1 at
<http://www.msapiro.net/mm/index_htdig.patch.2.1.18> (mirrored at
<http://fog.ccsf.edu/~msapiro/mm/index_htdig.patch.2.1.18>). When 2.1.19
final is released, a 2.1.19 version of the patches will be put in the
same directories.

Also, please read <http://wiki.list.org/x/4030645> for more
understanding of group mismatch errors.

After you restore the group and permissions on
/usr/local/mailman/cgi-bin/mmsearch, what are the results of

sudo -u apache /usr/local/mailman/cgi-bin/mmsearch


sudo -u mailman /usr/local/mailman/cgi-bin/mmsearch

Based on what you have posted so far, I think that running the command
as 'apache' will produce a 'we hit a bug' message and running the
command as 'mailman' will produce a group mismatch error. Is this the
case? If not, what do you see?

Also try it replacing 'mmsearch' with 'listinfo' and report those results.
