Hi,
  after updating org-mode and emacs to latest commits, I have seen that
some links to IDs in different files are exported like this:
<li>some link: <a href="otherfile.html#ID-id:c5m2je81pue0">link</a></li>

  Shouldn't it be?:   otherfile.html#c5m2je81pue0

  I didn't have time to debug this yet or see if it's from my setup. I may
do it in the next days.
