Summary:                    Access violation exception when calling
vtkRenderer::Render()
Description: 
The exception occurs on line vtkRenderer.cxx:660:
  for ( i = 0; i < this->PropArrayCount; i++ )
    {
    this->NumberOfPropsRendered +=
      this->PropArray[i]->RenderOverlay(this);
    }
this->PropArrayCount is 2, but this->PropArray is null

It seems that the exception is a result of not resetting PropArrayCount in
vtkRenderer::Render(). The lines 362ff in vtkRenderer.cxx are as follows:
  if ( this->PropArray)
    {
    delete [] this->PropArray;
    this->PropArray                = NULL;
    }

But PropArrayCount is not set to 0 after this. 

The exception occurs on the same object some time after these lines are
executed.
