[vtk-developers] Broken vtkDataSetReader ?

[Randall Hand]

You'll find a small attached dataset.

This dataset was generated with Paraview 2.0r3. I loaded up one of my 128^3 
datasets, and used the Extract Grid to pull a small 10^3 from it. When I 
load it with the latest CVS VTK, I get "null" for all the field names, but 
Paraview shows them correctly.
