Bug Description

Binary package hint: python2.7

The following script crashes python2.7 with enthought tvtk

#!/usr/bin/python

import numpy as np
from enthought.tvtk.api import tvtk
from enthought.mayavi.scripts import mayavi2

poly = tvtk.Polygon()
poly.points.from_array(np.array([
[0,-.5,0], [1.5,0,0], [0,1,0], [-2,0,0]]))
cells = tvtk.CellArray()
cells.insert_next_cell(poly)
pd = tvtk.PolyData(points=poly.points, polys=cells)

@mayavi2.standalone
