Oh dear, that really is quite a strange error message. Something is definitely wrong. Can you please make a ticket for it, and include instructions on how to reproduce it?
Done: http://hackage.haskell.org/trac/ghc/ticket/4355
I gather that it depends on other packages that themselves needed changes, so reproduction might not be entirely easy?
I've attached a module to the bug report that triggers the problem and only depends on base and mtl, so that should be fairly easy to reproduce. Regards Malte
