[Paraview] ParaView crashes trying to access property of Custom Reader

[Mike Jackson]

Now I get a "Frames Per Slice" label and associated Text field.  
Except I just want to display some information about the file. This  
will actually "set" the value in the vtkH5RoboMetReader object, which  
is what I don't want.

Is this a bug in PV 3.2.1? or should I be thinking of a custom panel  
at this point?
