check return value from auth_new_cal_from_source(). Connect to
2004-01-21 Rodrigo Moya <rodrigo@ximian.com> * gui/e-tasks.c (e_tasks_add_todo_source): check return value from auth_new_cal_from_source(). Connect to "backend_died" signal on the ECal class. (backend_died_cb): callback for "backend_died" that displays an error message when that happens. * gui/gnome-cal.c (backend_died_cb): use a GtkMessageDialog. svn path=/trunk/; revision=24355
