Drawing lines in <gnome-canvas>

[Marcello Mathias Herreshoff]

Hello,

I cannot draw lines in gnome canvases with guile-gnome-platform-2.7.95
(with Guile version 1.6.4).

Here is example code which should draw a red diagonal line:

--BEGIN--
(define w (make <gtk-window> #:type 'toplevel))
(define canv (make <gnome-canvas>))

(define the-line (make <gnome-canvas-line>
                   #:parent (root canv)
                   #:points #(0 0 100 100)
                   #:fill-color "red"))

(gtk-widget-show-all w)
(gtk-container-add w canv)
(gtk-main)
--END--

However, the above code generates the following error:

   ERROR: In procedure scm->gvalue:
   ERROR: Don't know how to make values of type #<gtype GnomeCanvasPoints>

Is this a guile-gnome bug or have I done something wrong?
