WrapITK with python wrapping on against ITK 3.10 produces the beow error. Seems HistogramToImageFilter should be corrected to HistogramToIntensityImageFilter.

This is a bug in ITK, fixed yesterday http://public.kitware.com/cgi-bin/viewcvs.cgi/Code/Numerics/Statistics/itkHistogramToIntensityImageFilter.h?root=Insight&sortby=date&view=log . Please use ITK cvs.
