 Take a look at these two URLs:

 http://www.nileguide.com/destination/blog/amsterdam/
 http://www.nileguide.com/destination/blog/Amsterdam/

 The first URL loads up the Amsterdam blog home while the second URL loads
 up a post on the Amsterdam blog that starts with the word "amsterdam." The
 reason for this is because !WordPress currently uses a case-sensitive
 match on [http://core.trac.wordpress.org/browser/trunk/wp-includes/class-
 wp.php#L164 line 164 in class-wp.php]. Since a case-sensitive match of a
 form of home_url() isn't found in the requested path, the request URL is
 never set up right. redirect_guess_404_permalink() ultimately ends up
 redirecting the request in this case.

 Changing the regex match to be a case-insensitive match on that line fixes
 the problem, but it also allows that blog to then be loaded from multiple
 URLs. Breaking canonical URLs like that would be bad obviously.

 It seems that functionality needs to be added to not only handle the
 canonical URLs for pages / posts, but also for blogs. I'm not familiar
 enough with that code to attempt a fix, but I wanted to bring it up anyway
 as this seems unintended.
