Tramp on 24.4/W32

[Fabrice Popineau <fabrice.popineau@gmail.com>]

Can anybody check if tramp is currently working on Emacs/W32 ?
I have tried a quick test and I can't seem to be able to save file on a 
remote Unix machine, at least not out of the box.

c:\>emacs -Q

eval :
(require 'tramp)
(setq tramp-default-method "pscp"
      tramp-default-user "someuser"
      tramp-default-host "somemachine.supelec.fr"
      )

C-x f /popineau@somemachine.supelec.fr:/path/foo.txt
<insert some chars>
C-x f

The trace in *Messages* is :

Any idea of what's going on ?

Thanks in advance,
