Here is a short version without kiwi requirement.

class CellRendererClickablePixbuf(gtk.CellRendererPixbuf):

    __gsignals__ = {'clicked': (gobject.SIGNAL_RUN_LAST, gobject.TYPE_NONE,
                                (gobject.TYPE_STRING,))
                   }

    def __init__(self):
        gtk.CellRendererPixbuf.__init__(self)
        self.set_property('mode', gtk.CELL_RENDERER_MODE_ACTIVATABLE)

    def do_activate(self, event, widget, path, background_area, cell_area,
                    flags):
        self.emit('clicked', path)
