[vtkusers] Cell data visualization for meshes made of parabolic tetra in vtk4.2 is crashing the application

[stefano perticoni]

Dear vtk users,

I'm trying to visualize cell data for meshes made of parabolic tetra with
vtk 4.2. Cell data visualization is crashing the application while point
data displaying is ok. Here is a little test program with some test data to
replicate the problem. To replicate the crash uncomment the "# PDM
SetScalarMode 2" line and comment the  "# PDM SetScalarMode 0" line.
Please let me know if I'm doing some mistakes trying to visualize this data.

Regards,
Stefano Perticoni
