Haskellmode-emacs 2.8.0, garbage in the echo area

[Lex F]

Hi everyone

I followed README for haskell-mode 2.8.0 and added (load
"haskell-mode/haskell-site-file") to my .emacs for GNU Emacs 23.2.1 on
Arch Linux. When I open any haskell (.hs) file, say xmonad.hs, I get
some garbage in my echo area It is

#[nil "\300C\207"
      [t]
      2]

It was also reported by someone else
https://bbs.archlinux.org/viewtopic.php?id=101031 but I don't like
their workaround.

Is it a bug?

Thanks,

Lex
