[Paraview] tables in multi-block datasets

Hi,

I would like to attach some tables of data to my multi-block dataset
(already containing volumes and surfaces) but many of the filters now cause
paraview to crash - i.e. cut, clip, extract threshold, etc.  The crash
happens because the filters do not check the SafeDownCast to a vtkDataSet.

Here is a Python script that reproduces this:

8<----------------------------------------------------
from paraview.simple import *
c = Cylinder()
h = Histogram()
g = GroupDatasets( Input=[ c, h ] )
s = Slice( SliceType="Plane" )
Show(s)
---------------------------------------------------->8

Can anyone suggest a better way to attach the data?

Thanks,
Paul
