[Wien] Persisting LOPW and LAPW1 errors - bug of nn?

The Te (prototype Se,hP3,152) structure has the Pearsonsymbol hP3 but the structure file contains 6 atoms,
the Wyckoff position is 3a and that has a multiplicity of 3 and not of 6.
I guess the z-parameter or anything else is wrong with the structure
that is most probably not a bug in the program

You are right, there seems to be a nn bug. This may explain everything
including the LOPW exhausted error.
