The launch helper does keep more information, but that information never 
leaves its process boundaries. It's one of these:

activation-helper.c:      dbus_set_error (error, 
DBUS_ERROR_SPAWN_SETUP_FAILED,
activation-helper.c-                      "could not clear environment\n");
--
activation-helper.c:      dbus_set_error (error, 
DBUS_ERROR_SPAWN_SETUP_FAILED,
activation-helper.c-                      "cannot find user '%s'\n", user);
--
activation-helper.c:      dbus_set_error (error, 
DBUS_ERROR_SPAWN_SETUP_FAILED,
activation-helper.c-                      "could not initialize groups");
--
activation-helper.c:      dbus_set_error (error, 
DBUS_ERROR_SPAWN_SETUP_FAILED,
activation-helper.c-                      "cannot setgid group %i", pw-
>pw_gid);
--
activation-helper.c:      dbus_set_error (error, 
DBUS_ERROR_SPAWN_SETUP_FAILED,
activation-helper.c-                      "cannot setuid user %i", pw-
>pw_uid);

All but one of them are in the function switch_user().
