I'm currently running beta 39 in Ubuntu.  I am using a simple scattering media,
40 intervals, scattering { 3, White*10^-obsceneNumber } samples 30, 50

I did notice that pov crashes with an out of memory error if I use 400 intervals

I am certain the light source is inside the sphere, though I have not tried
removing the csg.

This is not a new problem.  I've experienced similar difficulties in the past
with light sources inside csg objects.
