(e_addressbook_model_class_init): create the backend_died signal. (e_addressbook_model_init): init backend_died_id (e_addressbook_model_set_arg): disconnect the backend_died signal from the old book and hook it up to the new book. * gui/widgets/e-addressbook-model.h: add the backend_died signal. * backend/ebook/e-book.c (backend_died_cb): new function, emit the backend_died signal. (e_book_do_response_open): create the component listener and hook up the backend_died signal.
