You can do this by specifying the transparent color of the pixbuf.

You can use Pixbuf.AddAlpha ().  This will return a new pixbuf, as specified
by the gdk docs here:
http://www.pygtk.org/docs/pygtk/class-gdkpixbuf.html#method-gdkpixbuf--add-alpha

I don't think you need to mess with the .Pixmap of the image, just create a
new pixbuf from the file, add alpha, and assign the resulting pixbuf to
imgCartIcon.Pixbuf.
