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
