It assumes that the root folder has its own component registry, but
the rootFolder factory doesn't create one, so it returns none as the
next site manager. So, you need to call setSiteManager for the root
folder after creating it. However, I guess this case should be handled
by zope.site's event handler. I'll take a look at that tomorrow.
