Long story short:

 * Bug in fakeroot (#1023286 + #1024544)
 * Me thinking it was a bug in debhelper so I tried to fix it
   (which did not work and broke on the way in)
 * Me realizing it was a bug in fakeroot and my change did not
   even function as a work around, so I undid it (it broke on
   the way out as well).

And the winners are: All the people that have (and are) able to use 
"Rules-Requires-Root: no" as packages with that flag would have been
completely unaffected by this entire ordeal!

Your options include:

 * Migrate to "Rules-Requires-Root: no" if you can
 * Ensure you have debhelper (>= 13.11.3~) ("just uploaded") or
   debhelper/13.11.1 (or debhelper << 13.11)

I will now go back to looking more at my prototype for getting even more 
packages buildable with "Rules-Requires-Root: no".
