Could you check whether the problem also occurs with the current GHC 6.9 (development version)? There has been at least on bug that may cause this sort of problem been fixed in 6.9, which may not have been merged back to 6.8. (Remember that we unfortunately cannot support type families (and hence associated types) fully in 6.8 - this has been discussed previously on this and/or the Haskell lists.) Manuel
