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

[clinton at elemtech.com]

It wasn't really a bug, but a feature that wasn't asked for.

If you're using ParaView from CVS, you can update your code and try this.
Then you don't have to make your own panel.

        <IntVectorProperty
          name="FramesPerSlice"
          command="GetFramesPerSlice"
          information_only="1">
          <SimpleIntInformationHelper />
        </IntVectorProperty>
     <Hints>
       <Property name="FramesPerSlice" show="1"/>
     </Hints>
