And, yes. the problem is caused by the line
#toolbar button self.tb_button = gtk.ToolButton(rtm_menu_image)
where rtm_menu_image is a gtk.Image with the custom icon
which doesn't trigger the issue if it's changed in
#toolbar button self.tb_button = gtk.ToolButton(gtk.STOCK_CUT)
This way to create buttons should be the standard one. I don't know how could be improved. F-Spot, Evolution, Rhythmbox, Cairo-Dock all have bugs filed against them with the same issue... Maybe someone more expert could look into this.
