How do I open a file with IconFileSelect? (partially solved!!!)

def on_file_selected(self,widget,data=None):
    md = gtk.MessageDialog(None,
    gtk.DIALOG_DESTROY_WITH_PARENT, gtk.MESSAGE_QUESTION,
    gtk.BUTTONS_YES_NO)
    md.run()
    path = self.builder.get_object('file').get_selected()
    print path
    md.destroy()

class HandlerClass:
    def __init__(self, halcomp, builder, useropts):
        # make a class reference to builder 
        # (self.ANYTHING is available anywhere in the HandlerClas class)
        self.builder = builder

        # make a class reference to the open vcp_action
        self.open = builder.get_object('open')

        # change a property in the iconchooser so all programs show
        # this shouldn't be required - it's a bug
        builder.get_object('file').set_property("filetypes", '*')

    # This is a callback function from the icon chooser selected in the GLADE signal editor
    # in GTK the first variable is always the widget that owned the signal that called this function
    # any other variables depend on the widget, in this case icon view sends the path
    def on_file_selected(self, widget, path):
        print path
        if path:
