Here's a start for this one.

What happens if I configure it not to have either of these two modules? It
hangs for me.  Maybe because you took out the check below?  Maybe there
needs to be a new check for empty categories or an ifdef that gets rid of
categories that have no subcategories.

It works fine for me when I'm not trying to break it. :)

This check?
