Hello Sebastien,
I tried out your suggestion (I basically cut and pasted your small code 
into my .emacs file), but there must be something that emacs does not like.
First of all, was I supposed to simply introduce those lines in my 
.emacs file? Any position in the emacs file can do?
I installed  emacs 22.1 with gtk from the standard Debian testing 
repositories and I have my own .emacs file for some simple 
customization. In the following, I report the error message returned by 
emacs.
Cheers

Lorenzo
