Comment (by goldfire):

 Not quite. This problem existed before `TypeInType` and continues to
 exist. It's just that my (new) implementation of `tcTyClTyVars` gets
 thrown off the scent by the `SigTv`s. But I'm pretty sure I have a fix for
 that, totally orthogonal to any fix for this ticket. I'll get the (quite
 local) fix in soon.
