What if anything is in the Apache error_log?

The cgi-wrapper is invoked by the web server. It checks the callers
group and then calls scripts/driver which in turn runs the actual
Mailman/Cgi/* script.

Normally, exceptions encountered by the admin.py, listinfo.py, etc.
script are reported by the driver with a full traceback.

It seems in this case the driver script encounters the Operation not
permitted exception either before or in the process of trying to print a
traceback.

See the comments at the beginning of scripts/driver.

You can manually run as root or a user in Mailman's group

export REQUEST_METHOD=GET
python /path/to/scripts/driver listinfo

and see what that produces.
