Subject: Fixes #33078

2005-01-28  Rodrigo Moya <rodrigo@novell.com>

	Fixes #33078

	* gui/gnome-cal.c: deal now with categories entirely here, no more
	"categories_changed" signal from the backends.
	(free_categories, add_categories, append_category_cb,
	client_categories_changed_cb, copy_categories): removed.
	(gnome_calendar_add_source): don't connect to removed signal.
	(gnome_calendar_destroy): destroy the config listener.
	(gnome_calendar_init): create a listener for the categories list
	GConf key.
	(config_categories_changed_cb): callback for configuration changes
	in category list.
	(setup_widgets): initialize the search bar with categories from
	the configuration.

	* gui/e-tasks.c (client_categories_changed_cb, e_tasks_add_todo_source,
	e_tasks_init, config_categories_changed_cb, e_tasks_destroy,
	setup_widgets): same as gnome-cal.c.
