None RINDEX in world volume and subvolume causes hang

I just downloaded the latest copy of Geant4 onto a new machine and attempted to build a basic optical simulation involving the generation of Cerenkov photons. My current geometry is a world volume, and a single G4Box contained completely in the volume. The Physics List is copied directly from another optical code that runs correctly on this machine. I'm generating a single electron from a GeneralParticleSource and firing it through the G4Box.

When the world volume as a MaterialPropertiesTable with an assigned RINDEX, but the G4Box does not, the simulation runs correctly. If the box has a defined RINDEX, but the world volume does not, the simulation runs correctly. If the world volume AND the G4Box have defined RINDEX values, then the simulation occupies an entire core at 100% utilisation and hangs indefinitely.

The code is available at: https://github.com/rprechelt/OpticalTest

I would appreciate any insight into this behaviour - whenever there is a boundary between two materials with defined RINDEX's, my simulation hangs with 100% CPU utilization.
