  In a series of papers we have developed the method of iterated sector
decomposition for the calculation of infrared divergent multi-loop integrals.
Here we apply it to phase space integrals to calculate a contribution to the
double real emission part of the e+e- -> 2 jets cross section at NNLO. The
explicit cancellation of infrared poles upon summation over all possible cuts
of a given topology is worked out in detail for a specific example.
