By rwallace:

I looked into this a little bit earlier this week. I tried various implementations of `ListT` on Haskell and they all have this same problem. So I asked the [list](http://www.haskell.org/pipermail/haskell-cafe/2012-February/099282.html) and Oleg said that that particular `MonadPlus` law is hotly debated.

Perhaps we should just disable the test for that law?
