  We show that the axiom of Felder and Kazhdan on the vanishing of the
cohomology groups in negative degree associated to solutions of the classical
master equation in the Batalin-Vilkovisky formalism is violated by the spinning
particle in a flat background coupled to D=1 supergravity. In this model, there
are nontrivial cohomology groups in all negative degrees, regardless of the
dimension of the spacetime in which the spinning particle is propagating.
