Putting an image on the GnomeCanvas in Gnome-Perl

[dov imagic weizmann ac il]

In order to port some of my image viewing tools from Perl::Tk to
the Perl-GnomeCanvas I need to be able to show images on the
canvas. But appearently this functionality is broken in Gtk-Perl-0.6123 .
My guess from looking at the source in the CVS version is that it
doesn't work there either. I have created an example below, which
shows the problem. To test it just run the script. The fact foo.ppm
doesn't exist is irrelavent to the failure which is:
  
   Cannot set argument of type GdkImlibImage (fundamental type GtkBoxed)
   at ./img-on-canvas line 42.

Does anyone (which probably includes only Kenneth or Paolo) have any
idea of what is going on?

Regards,
Dov
