I failed to reproduce this error.

Could you apply the following patch, and report the result of
  grep "</div>\|<div" | grep -v "<div.*</div>
(find all opening and closing <div> elements, but omitting
those which are opened and closed in the same line)?

gitweb: Mark closing </div>'s in code and output
    
Add Perl comments and HTML comments (<!-- ... -->) to </div> output,
to mark which 'div' element the closing </div> corresponds to.
