Comment (by bgamari):

 Interesting, I excluded my hypothesis after noticing that the following
 testcase indeed fails with a proper error:
 {{{#!hs
 {-# LANGUAGE TemplateHaskell #-}

 module T10047A where

 import Language.Haskell.TH

 -- Passing var name to conE should fail.
 x = $(conE 'id)
 }}}
 I didn't look much farther after this.

 Quite interesting that `mkNameG_v` gets around the error. Are you going to
 continue looking into this or should I add it to my queue?
