[xmonad] Re: Issue 336 in xmonad: xmonad won't start: Irrefutable pattern failed for pattern (Data.Maybe.Just nbc_)

Comment #9 on issue 336 by rwsims: xmonad won't start: Irrefutable pattern failed for pattern (Data.Maybe.Just nbc_) http://code.google.com/p/xmonad/issues/detail?id=336 FYI, I get this error on 10.5.8, xmonad 0.9.1 from cabal; so it doesn't seem to be limited to Snow Leopard. I tried copying over the xmonad binary from ~/.cabal/bin, but didn't seem to help.
