Fixes #39740

2003-03-14  Rodrigo Moya <rodrigo@ximian.com>

	Fixes #39740

	* gui/e-meeting-model.c (is_cell_editable): check row number is valid
	before using it as index for the GPtrArray.

2003-03-14  Rodrigo Moya <rodrigo@ximian.com>

	Fixes #39356

	* gui/Makefile.am:
	* gui/tasks-migrate.[ch]: removed tasks migration obsolete stuff.

	* gui/calendar-component.c (owner_set_cb): don't call tasks_migrate.
