`g_file_enumerator_finalize` should not call `g_file_enumerator_close` because object parts (i.e. subclass variable and/or resources) might already be freed, causing memory safety issues. A better place to call `g_file_enumerator_close` is `g_file_enumerator_dispose` because it is safe to access the object memory here. Fixes #3713 Signed-off-by: fbrouille <150549-fbrouille@users.noreply.gitlab.gnome.org>
