Comment (by kurtmckee):

 Unfortunately I don't have a clean install, and after looking at the feed
 more carefully this morning the contents of the `description` element
 aren't even a consistent word count nor byte length. The problem with the
 feed is probably an issue with a plugin or theme customization, as you've
 noted.

 Before closing this ticket, is my concern about `trackback_url_list()`
 valid? The PHP documentation suggests that using `substr()` on a UTF-8
 string can produce truncated byte sequences. At
 [https://core.trac.wordpress.org/browser/trunk/wp-includes/post.php#L3092
 line 3092 in wp-includes/post.php]:

 {{{
 if (strlen($excerpt) > 255) {
     $excerpt = substr($excerpt,0,252) . '...';
 }
 }}}
