The function in Law2_Dem3DofGeom_FrictPhys_CundallStrack (or what is it
called) was commented out because of this bug, and I think it is not
clear if it was a problem in that function or elsewhere in Dem3DofGeom.

I agree that there is no reason to report bugs agains Dem3DofGeom
anymore, as there would be no-one to fix them.

Bug description:
  When I run examples/rotatingCylinder.py with bzr2255 (default profile) I got a crash after several iterations. Seems it related with velocityBins mechanism:
