Comment (by bgamari):

 Hmm, I suspect the issue here is that we are not emitting the `Typeable`
 `TyCon` bindings into `hi-boot` files. This means things blow up when when
 the typechecker goes to construct `Typeable` evidence when only a `SOURCE`
 import of the module defining the type in question is in scope.
