	Can you reproduce the bug with the headsq dataset (VTKData/Data/headsq)


VTK_DATA_ROOT = vtkGetDataRoot()

# Start by loading some data.
v16 = vtk.vtkVolume16Reader()
v16.SetDataDimensions(64, 64)
v16.SetDataByteOrderToLittleEndian()
v16.SetFilePrefix(VTK_DATA_ROOT + "/Data/headsq/quarter")
v16.SetImageRange(1, 93)
v16.SetDataSpacing(3.2, 3.2, 1.5)
v16.Update()
