"This" being what?

I assumed that "refuses to do anything useful" means you cannot visit
a file, edit it, and save it.  That works for me, both in 24.3 and the
current trunk.  FWIW, I did

   HOME=/whatever emacs -Q

and in that session I could visit files, edit them, and save them.
Sure, Emacs bitched at me at startup, but that's it.
