I think I have fixed that bug (and the other one). It was introduced
by the multithreaded code, and was affecting only images with a
different size on the first and the last dimension, and when running
the filter with 3 threads or more. It was not related to 3D images.
Please update your copy of ITK, and tell me if everything is ok!
