This bug appears to be fixed in QuickCheck 2. However, for some reason cabal-install by default only installs 1.2. You have to explicitly ask for the newer version:

$ cabal install QuickCheck-2.1.0.1

cabal-install only installs 1.2 because QC 2 breaks a lot of packages (different function names, no coarbitrary, etc. IIRC). -- gwern
