MillerIndex is not exposed correctly to python

When build a MillerIndex in python I get the following error message:

Traceback (most recent call last):
  File "d19-workflow.py", line 303, in <module>
    mill = nsx.MillerIndex(peak,uc)
  File "/home/pellegrini/git/nsxtool/build/swig/pynsx.py", line 1188, in __init__
    this = _pynsx.new_MillerIndex(*args)
NotImplementedError: Wrong number or type of arguments for overloaded function 'new_MillerIndex'.
  Possible C/C++ prototypes are:
    nsx::MillerIndex::MillerIndex()
    nsx::MillerIndex::MillerIndex(nsx::MillerIndex const &)
    nsx::MillerIndex::MillerIndex(int,int,int)
    nsx::MillerIndex::MillerIndex(sptrPeak3D,sptrUnitCell)
    nsx::MillerIndex::MillerIndex(Eigen::RowVector3i const &)
