We present a novel source for supersymmetry breaking in orientifold models,
and show that it gives a vanishing contribution to the vacuum energy at genus
zero and three-half. We also argue that all the corresponding perturbative
contributions to the vacuum energy from higher-genus Riemann surfaces vanish
identically.
