    if os.environ.has_key('REMOTE_HOST'):

    elif os.environ.has_key('REMOTE_ADDR'):
        return os.environ['REMOTE_ADDR']
    else:
        return None
--------------------------------------------------------------------------
I write a simple HTML code to invoke the script.
<form method="POST" action="/mailman/oz_subscribe/oztime_tech">
  <p>Please Input you email addr:  <input type="text" name="email"
size="20"><input type="submit" value="subscribe to" name="subscribe"></p>
</form>
---------------------------------------------------------------------------
oz_subscribe is a CGI program produced by a script(PY) file with same name.
oztime_tech is a MailList name.

But I get a error msg

Bug in Mailman version 2.0rc1

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.

So I go to see the error log.I found nothing.(Before did these.I simply
cleared all content in the error log file)

Why?Who can help me?
