Various issues with history topic

I see a few issues with the topic history screen:

History doesn't show document changes

If you take a look at the history for this page, you should see several changes to this text, as I've edited in in a few passes, with changes to the other fields in between. However, it only shows the initial text creation in the history.

Linked item on document history is mysterious

On the line showing the creation of this text, there's a link to what I presume is the document itself. In this case, this link:

http://www.freebase.com/view/guid/9202a8c04000641f80000000042b3e84

viewing that shows a mangled title bar (with misplaced HTML) and a mysterious view of something that has no history at all.

History next button appears when there is nothing else to show
