No, that's a buglet. The archive link is not functional until at
least one message has been posted to the list.

I'm sure you know that if the error occurs because of a gid mismatch,
in either the CGI wrapper or the mail wrapper, errors are only logged
to syslog, not to $prefix/logs/error. For mail, you ought to also get
a bounce containing the error message, and for CGI -- with the next
version -- you will get a more useful Web diagnostic page.
Once control has been passed to the Python world (e.g. the `driver'
script for CGI, or `post' for mail), then errors get logged to
Mailman's log files. Note that a misconfiguration of syslog or your
mail system might mean that those pre-Python errors are getting lost.
[This is probably more useful to mailman-developers]
Once you're in the Python world, there are several ways to log error
messages for debugging. My favorite is, once I have a MailList
object, I like to call the LogMsg() method with kind=='debug', kind of
mlistobj.LogMsg('debug', 'I got to here: %s', 'foo method')
This will timestamp the message, and write it to $prefix/errors/debug.
