Dunno.  AFAIK, it can happen that the newly created frame is not yet
displayed (i.e., created by X) when `after-make-frame-functions' are
called.

Try to use a delay, like this:

(add-hook 'after-make-frame-functions
          (lambda (frame)
            (run-with-idle-timer 1. nil 'raise-frame frame)))

Note that `raise-frame' doesn't make the frame "current".  Maybe Gnome
raises the frame that has focus automatically?  Then you want
`select-frame-set-input-focus' instead of `raise-frame'.

If your problem is specific to emacsclient invocations, it is probably
better to configure `server-window' instead of
`after-make-frame-functions'.  This is what I do:

(setq server-window
      (lambda (buf)
        (let ((win (display-buffer-pop-up-frame buf ())))
          (select-frame-set-input-focus (window-frame win)))))

Hope one of the above proposals helps.

Michael.
