haskell-indentation-mode parse error on indenting import declaration

[ryantm]

When I use MELPA version 20141212.1131 of the haskell-mode, and a file containing:

module A where

import Control.Concurrent
  ( forkIO
, killThread)

and I put the point at the "k" in killThread and type tab, it prints "Parse error" in the minibuffer and it does not change the indentation.

Confirmed. More completely:

Debugger entered--Lisp error: (parse-error . "Illegal token: layout-next")
  signal(parse-error "Illegal token: layout-next")
  parse-error("Illegal token: %s" layout-next)
