[Paraview] Can't undo after changing tabs in Object Inspector

[Geoff Draper]

Here's how to duplicate this condition:

1. Start with an empty scene.
2. Create a primitive shape, i.e. Sources -> Cone
3. Click the "Apply" button in the Properties tab of the Object Inspector.
4. Click either the Display or Information tab in the Object Inspector.
5. Click the "Undo" button on the toolbar (or Ctrl-Z).
6. ParaView crashes, with an output message of:
"""
    "ERROR: In ..\..\..\Servers\Common\vtkProcessModule.cxx, line 1091
    vtkProcessModule (0850F950): Object type: vtkSMAnimationSceneProxy,
    could not find requested method: "SetAnimationTime"
    or the method was called with incorrect arguments.

    while processing
    Message 0 = Invoke
      Argument 0 = id_value {15}
      Argument 1 = string_value {SetAnimationTime}

    ERROR: In ..\..\..\Servers\Common\vtkProcessModule.cxx, line 1092
    vtkProcessModule (0850F950): Aborting execution for debugging purposes.
"""

I'm using Windows Vista, Visual Studio 2005, and ParaView source code 
checked out from CVS earlier today.

Thanks for any insight you could offer,
Geoff
