I'm not sure how the XsessionErrors.txt got attached to this issue but it hasn't anything to do with the problem. Sorry for the inconvenience.

Fixed with the latest rebuild in lucid. If you're not using lucid, you can only install it with the ghc6 version shipped, not a newer one from a PPA. Otherwise you'd need to rebuild the haskell stack on your own.
