** Fix for bug #576921

2009-03-28  Hiroyuki Ikezoe  <poincare@ikezoe.net>

	** Fix for bug #576921

	* mail/em-mailer-prefs.h: Remove needless GtkListStore objects.
	* mail/em-mailer-prefs.c: Use dispose instead of finalize.
	(em_mailer_prefs_dispose): Unref header_list_store.
	(init_junk_tree), (init_label_tree): Returns gboolean value instead
	of GtkListStore object. Unref GtkListStore right after
	gtk_tree_view_set_model.
