              I was able to reproduce the error message. For some reason IText isn't putting in decode param for the CCITTFax image. By default the k=0 which specifies a T4 1D fax format. However the image streams appears to be encode using k = -1 which T6 encoding.

              I'm going to attach a patch that addresses the issue in that it get the PDF to render. Before the next release I'll take another look as there maybe a image header that we can use to figure out the k value more reliably.

              Patch to get around the missing k value.
