The library is shipped with ghc, and the darcs repository lists
libraries at haskell.org as the maintainer, so GHC's trac seems to be the
right place.

I've created a ticket for this now, See
    http://hackage.haskell.org/trac/ghc/ticket/2227

Note that I opted for reimplementing the whole module instead of
just fixing the bug.
