NULL the handle after a failed open so the offline handler won't think

2001-10-26  Iain Holmes  <iain@ximian.com>

	* e-summary-rdf.c (open_callback): NULL the handle after a failed
	open so the offline handler won't think they're still open.
	(e_summary_rdf_set_online): Cancel all the open connections when the
	summary goes offline.

	* e-summary-weather.c (open_callback): NULL the handle after a failed
	open so the offline handler won't think they're still open.
	(e_summary_weather_set_online): Cancel all the open connections when the
	summary goes offline.

	* e-summary.c (e_summary_set_online): Call the callback if it's not
	NULL.
