1) you didn't write "rprim", so it has defaulted to cubic (this is incidental)

2) you don't specify ngkpt or kptrlatt  -  this should be enforced. If
you do either, it works. Strangely, if you leave kptrlatt at certain
values it still stops. Not clear why yet, but in any event it doesn't
make much sense to run without setting ngkpt or kptrlatt.
