I tried to solve the examples/diffusion/poisson_short_syntax.py using simple.py. The solution completes by when I try to visualize cylinder.vtk with postproc.py, I get the following error:

In C:\Python27\lib\site-packages\mayavi\sources\vtk_xml_file_reader.py: 86
AttributeError: 'AlgorithmOutput' object has no attribute 'point_data' (in get_all_attributes)

The above error is in a dialog box. when I click ok, the postproc window opens with no geometry shown. I have tried visualizing the vtk file in paraview and that shows a reasonabel t profile.

Additionally, the error log is in the attached file. Please tell me how to solve this problem.
