Yes, too different:
linux 2.6.23 / python 2.5.1 / gtk+ 2.12.1 / pygtk 2.12.0

Anyway .set_image() method is available in pygtk 2.6 and above[0], (I suppose
you have =>pygtk-2.6)
May be you must check that "gtk-button-images" property is True. (Available in
GTK+2.4 and above)

>>> settings = button.get_settings()
>>> settings.get_property("gtk-button-images")
True

And as a last option you can write your own custom button.

# only work when we set stock item via constructor
class CustomButtom(gtk.Button):
    def __init__(self, stock=gtk.STOCK_ADD):
        gtk.Button.__init__(self, stock)
    def set_image_or_label(self, stock_item=None, label=None):
        if stock_item:
            self.set_label(stock_item)
        al = self.get_children()[0]
        hb = al.get_children()[0]
        image, text = hb.get_children()
        if label:
            text.set_text(label)
        else:
            text.set_text('')
