Comment (by bgamari):

 Replying to [comment:10 simonpj]:
 > Ah, here's a possibility. The `tcdSigs` for classes used to contain a
 `TypeSig` for each method, but now it contains a `ClassOpSig`. Maybe
 Haddock is expecting the former but only finding the latter?

 Indeed, I've worked that much out and I've found all of the obvious places
 where this needs to be accounted for. Unfortunately it seems I'm missing
 one of the non-obvious ones.

 For those playing along at home I'm working
 [[http://github.com/bgamari/haddock/tree/work|here]].
