Problem with gtk drawing primitive

[Jerome Blondel <jeromeblondel yahoo fr>]

Hi

I'm making a widget from scratch using the tutorial's GtkDial as a base. 
For now I  just want to draw something in my widget. The following error 
occurs

(test_sw:4242): Gtk-CRITICAL **: gtk_paint_polygon: assertion 
`style->depth == gdk_drawable_get_depth (window)' failed

This is the code in the WIDGET_expose callback:

blankstyle = gtk_style_new();
blankstyle->bg[GTK_STATE_NORMAL] = sw->color;
gtk_style_set_background(blankstyle, w->window, GTK_STATE_NORMAL);
gtk_paint_polygon(blankstyle, w->window, GTK_STATE_NORMAL, GTK_SHADOW_OUT,
                 NULL, w, NULL, points, 8, TRUE);

Please could anyone help me with this problem?
