Yes - I was being stupid - I thought you were referring to an elisp
function! :-;

If I "xdg-open ." from the command line it works great.

If I change xdg-open for nautilus in the code below it works. (Using
nautilus that is).

But using xdk-open there it does not work for me (debian). Does it work
on your Linux install?

-->-->--
(defun dired-open-externally ()
  "Open the current directory in your OS's file manager."
  (interactive)
  (let ((fileobject (dired-get-file-for-visit)))
        (start-process "dired-external" nil "xdg-open" fileobject)
        (message "file is %s" fileobject)
        )
)

(define-key dired-mode-map (kbd "e") 'dired-open-externally)
