Comment (by roganty):

 I have been doing a little bit of digging around in canonical.php and have
 found that $requested_url is never the same as $redirect_url

 The following bit of code shows some print statements and die() functions
 that I have added to canonical.php

 {{{
 function redirect_canonical($requested_url=NULL, $do_redirect=true) {
         global $wp_rewrite, $posts, $is_IIS;
 print "\r\n<br />".$requested_url." ";
 [...cut...]
         if ( $redirect_url && $redirect_url != $requested_url ) {
                 // var_dump($redirect_url); die();
 print "1:".$redirect_url."|".$requested_url." ";
                 $redirect_url = apply_filters('redirect_canonical',
 $redirect_url, $requested_url);
                 if ( $do_redirect) {
 print "2:".$redirect_url."|".$requested_url." ";
                         // protect against chained redirects
                         if ( !redirect_canonical($redirect_url, false) ) {
 print "3:".$redirect_url."|".$requested_url." ";
 die("Die:1");
                                 wp_redirect($redirect_url, 301);
                                 exit();
                         } else {
 die("Die:2");
                                 return false;
                         }
                 } else {
 die("Die:3");
                         return $redirect_url;
                 }
         } else {
 #die("Die:4");
 print "FALSE ";
                 return false;
         }
 }}}

 If I go to [http://www.roganty.co.uk/blog/2007/12/ /blog/2007/12/] I get
 the following output:
 {{{
 <br />
 1:http://www.roganty.co.uk/blog/2007/12/|http://www.roganty.co.uk/blog/index.php?year=2007&monthnum=12
 2:http://www.roganty.co.uk/blog/2007/12/|http://www.roganty.co.uk/blog/index.php?year=2007&monthnum=12

 <br />http://www.roganty.co.uk/blog/2007/12/
 FALSE3:http://www.roganty.co.uk/blog/2007/12/|http://www.roganty.co.uk/blog/index.php?year=2007&monthnum=12
 Die:1
 }}}

 On any other page I get the following output (followed by the rest of the
 page):
 {{{
 <br /> FALSE
 }}}
