PyGTK calls locale.setlocale() and thus may be affecting

It's not a problem with your points lying inside a triangle. There is some
other
problem with the construction of the Delaunay triangulation. Sometimes the
algorithm fails. This is one way that it fails.

You have a new.py module somewhere which is interfering with the s
ixel in the colormap. This would give
more
reasonable results even with misapplied colormaps. However, it will probably be
less efficient to implement.

No, it was built against a dynamic freetype library which was not included with
