[cctbxbb] flex.histogram giving ArgumentError when arguments correct

[Winter, Graeme (DLSLtd,RAL,LSCI)]

Hi Tristan

Given that it worked for other integers as input (as shown further down) I’d hope this makes no difference however 

    H = flex.histogram(data=coords, data_min=0.0, data_max=float(dim), n_slots=dim)
Boost.Python.ArgumentError: Please report this error to dials-support at lists.sourceforge.net: Python argument types in

Nope :-( 

It still fails… 

This one is properly weird…

Thanks Graeme
