[Pkg-haskell-maintainers] Bug#630092: After upgrade from 0.9.1 to 0.9.2: "Error detected while loading xmonad configuration file"

[Benno]

Package: xmonad
Version: 0.9.2-2+b1
Severity: important

After safe-upgrading xmonad to 0.9.2 in debian testing xmonad starts with following error message:
>   Error detected while loading xmonad configuration file: /home/benno/.xmonad/xmonad.hs
>
>   Please check the file for errors.

Recompiling with "xmonad --recompile" shows the same behaviour.
So I tried a very minimalistic xmonad.hs:
> import XMonad
> 
> main = xmonad defaultConfig

The result was the same.
