I think you are right, and I think I localized the problem.  EMIN in
case.in2 was set too large (0.53 to be precise).  Thus in case.output2
the band energies were reasonable, but the occupations were all zero.  I
have to wait for my batch job to start, but this looks promising.

The EMIN was probably a leftover from a charge distribution calculation.

Thanks for the help!
