I use following code and it works ok for me (I use GTK+ 2.0.3 on Windows)
gtk_widget_set_size_request(
    GTK_WIDGET (lookup_widget (GTK_WIDGET (EditWindow), "EditDrawingArea")),
    project->layerwidth, project->layerheight);

May be you does not assign right value to your main_draw variable? :-)
Try assert().
