Comment (by johnjamesjacoby):

 Something in [19918] broke post ancestors, specifically for bbPress 2.0
 and 2.1.

 Previously, forums, topics, and replies (all custom post types) would come
 with their ancestors pre-populated so they could be walked up through
 their forums to root. Now sometimes there are no ancestors, so things like
 breadcrumbs are showing inaccurate results.

 I've only been able to track it down to being inconsistent ancestor
 results in the cache; I haven't come up with the best place to drop in a
 fix. Most likely a call to _get_post_ancestors( $_post ); is needed
 somewhere.
