[Paraview] Reader did not create output

[Berk Geveci]

I couldn't see anything obviously wrong. Try setting a breakpoint in
vtkDemandDrivenPipeline::CheckDataObject right before you open the
file. When you walk over that function, is there an output at all? If
no, is DATA_TYPE_NAME() set to anything?
