Still not sufficient. I don't see where (stringp nil) is called.
"/ftp:mafreebox.freebox.fr:" is a string (obviously). The other
parameters of `file-remote-p' are optional, it is OK to be nil.

What happens, if you eval in your *scratch* buffer

(file-remote-p "/ftp:mafreebox.freebox.fr:" nil nil)

What happens, if you move your ~/.netrc away (temporarily)?

Best regards, Michael.
