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.
