I call it like this:

        self.xml.connect_signals({
            "on_add_clicked"        : self.on_add_clicked,
            "on_remove_clicked"     : self.on_remove_clicked,
            "on_up_clicked"         : self.on_up_clicked,
            "on_down_clicked"       : self.on_down_clicked,
            "on_setup_clicked"      : self.on_setup_clicked,
            "on_clear_clicked"      : self.on_clear_clicked,
            "on_save_clicked"       : self.on_save_clicked,
            "on_open_clicked"       : self.on_open_clicked,
            "on_edit_clicked"       : self.on_edit_clicked,
            "on_book_ok_clicked"    : self.on_book_ok_clicked,
            "destroy_passed_object" : self.close,
            }

Since there is a second top-level in the glade file, I now have to add
these dummy entries to the first call:

        # Insert dummy handlers for second top level in the glade file
            "on_booklist_ok_clicked"    : lambda _:None,
            "on_booklist_delete_clicked": lambda _:None,
            "on_booklist_cancel_clicked": lambda _:None,
            "on_booklist_ok_clicked"    : lambda _:None,
            "on_booklist_ok_clicked"    : lambda _:None,

Note 1: The dummy handlers get replaced with real handlers when I
activate the second toplevel

Note 2: This seems to have started when I converted old glade files to
use builder.
