The extra code that shows up look like this:
<ac:task-list>
<ac:task>
<ac:task-id>5</ac:task-id>
<ac:task-status>incomplete</ac:task-status>
<ac:task-body><span><ac:link><ri:user ri:userkey="8a948101409bc57801409bc5c3c30030" /></ac:link> will follow up with developers</span></ac:task-body>
</ac:task>
</ac:task-list>
I also just noticed that these pages use Excerpts.
