Barry,

I added the line,
call MatSetOption(pcmat,MAT_NEW_NONZERO_LOCATION_ERR,PETSC_TRUE,ierr),
after the call to matrix assembly and do not get an error associated 
with the nonzero locations.

Here is the error running superlu_dist with one processor.

  0 SNES Function norm 9.448256037271e+02
        Nonzeros in L       21005940

        nonzeros in L+U     41958975
        nonzeros in LSUB    3914621
