In which call?  Could you try this:

  id = tvtk.ImageData()
  id.scalar_type = 'float'
  id.set(origin= ...)
  id.update()
  src = VTKDataSource(data=id)
  return src

Hmm, strange, I have never needed to set this at all.

A reproducible example would really help.

Yes, I tried that like this, but that should be the same.

r = tvtk.StructuredPoints(origin=zzz.origin(),dimensions=zzz.dims(), spacing=zzz.spacing(), scalar_type='float')

Well since this is not a fatal error, I will leave it. I still think this may be related to the fact that
ImagePlaneWidget inherits the lookup table if present, but also has it's own.
