Creating a new "Link to a Document" opens Word document or upload document dialog - plus more!

The Link to Document content type seems to be corrupted at root. When I attempt to create a new Link, either Word opens with a blank document or the "Upload" document dialog opens. It's been changing as I investigate.

One things I've noticed is that the "Link to a Document" Content Type on the parent site collection now shows it's parent as Document. this explains why the Word document opens, but not why the Upload dialog does.

While writing this question, I decided to check further and it seems that the other document types, Audio, Video etc.  all now have Document as the parent and are opening a blank Word document.

Has anyone seen this behavior? How do I fix this?

This is on SharePoint 2010.

Thanks in advance.
