[Paraview] error with python state file

[pat marion]

The problem in general is-  the script calls Show() and depending on the
dataset, paraview creates either a "GeometryRepresentation" or a
"UnstructuredGridRepresentation".  The script expects one type of display to
be created, but when it is executed with a different dataset (or possibly
the same dataset but different blocks toggled) a different type of display
is created.  The different display types have different properties.  The
script tries to set properties on the display that do not exist and fails.

I think it would be worth making a bug report for this and maybe we can come
up with a solution to avoid this in future versions of paraview.
