links to other nodes are broken in many posts

when participating in various issues or forums, i'm in the habit of including links to relevent other nodes via the html:

<a href="node/XXXXX">node/XXXXX</a>

or, just:

<a href="node/XXXXX">#XXXXX</a>

unfortunately, these posts now include links to:

http://drupal.org/node/node/XXXXXX

(note the double "node/") instead of where they used to point:

http://drupal.org/node/XXXXXX

here are a few examples:
http://drupal.org/node/52051#comment-80438
http://drupal.org/node/54974#comment-84688
http://drupal.org/node/53870#comment-84549

when i try on a test site running cvs drupal, these sorts of links work just fine, and they worked before the upgrade. don't really know what to suggest but i suspect the admins will have a good idea once they know it exists.

thanks!
