set op->listener to NULL to catch possible use of freed op

2001-08-05  Radek Doulik  <rodo@ximian.com>

	* backend/ebook/e-book.c (e_book_do_response_get_view): set
	op->listener to NULL to catch possible use of freed op
	(e_book_do_response_get_changes): ditto

	* backend/ebook/e-book-view-listener.c
	   (e_book_view_listener_check_queue): this callback could be (and
	   indeed is) called from signal emited above,
	   signal handler could call e_book_view_listener_stop, so we need
to check
	   if idle is still set and if not we don't want to unref again
