[Wien] Monoclinic (space group P-1) does not converge with spin-orbit (SO).

Hi!
I tried to run a calculation on a monoclinic system using WIEN2K_03
version. Without SO the calculation converged but with SO the
calculation did not converge even with very small mixing parameter
(PRATT 0.01). Using WIEN97 I was able to do the calculation with SO.
I think that WIEN2K_03 has a bug for the monoclinic symmetry with SO.
I will include the structure file for the system:
