------------------------+---------------------------------------------------
 In trying to debug the problem with my bbPress implementation on my SunOS
 host, it became very important to know who generated the 404 errors I
 encountered when browsing to my bbPress home directory.  Specifically, I
 needed to know who was reporting the 404 error (i.e. who was calling
 '404.php' in the selected template), and what uri was considered bad.  To
 do this, I enhanced the 404.php module and added a single line to
 bb_repermalink.  The simple changes greatly assisted in determining the
 problem.

 I would submit them as an enhancement for future releases.

 First, I created a GLOBALS variable as follows, in bb_repermalink:

 {{{
         if ( $check != $uri && $check !=
 str_replace(urlencode($_original_id), $_original_id, $uri) ) {
                 if ( $issue_404 && rtrim( $check, " \t\n\r\0\x0B/" ) !==
 rtrim( $uri, " \t\n\r\0\x0B/" ) ) {
                         status_header( 404 );

                         $GLOBALS['bad404url'] = 'From functions.bb-
 core.bb_repermalink $uri: >' . $uri . '<';

                         bb_load_template( '404.php' );
                 } else {
                         wp_redirect( $permalink );
                 }
                 exit;
         }


 }}}

 And the 404.php code was modified slightly (I'm using the default
 'Kakumei' template:


 {{{
 <h2 id="http404"><?php _e('Page not found!'); ?></h2>

 <p>
   <?php _e('I\'m sorry, but there is nothing at the URL:'); ?><br/>
   <b><?php
     _e($GLOBALS['bad404url']);?>
   <br/></b>

   <!-- //_e('['); _e(strlen($GLOBALS['bad404url'])); _e(' bytes]');
 ?><br/></b> -->
 </p>

 }}}

 The basic intent here is to not just tell the user that there is a '404
 Error', but to give him (and us) at least some hint as to who threw the
 error and why.

 I'm attaching a screen-shot of the result on my own site.
