I think that found the answer.
It is in decoration.py. Padding.rows() causes this exception. Looks
like the calculation doesn't include the padding margin. I made the
following change and it works. I am not sure if this enough as a
general fix. It doesn't do anything with the CLIP case yet.
thanks,
