You are using a function that is not working after the latest changes
in XMonad (take into account that the darcs version, while very
stable, still is a work in progress and sometimes the Contrib modules
are a bit out of sync).

We have 2 ways now:

1. the best thing is to start with a new, fresh Config file: save the
   one you are working on and issu the darcs revert command:
   darcs revert Config.hs
   Then rewrite your personalization from scratch and see what fails.

2. send here the offending lines (arounf Config line 170), so that I
   can understand the specific issue with the offending function and
   try to give you an answer.

Let me know.
