This is somewhat related to bug 690867 - the file has an image with an unusual
color space; before Michael's recent ICC work some of them are embedded as is
and stripped of the colorspace info (small but wrongly, like bug 690867) or
rendered correctly but with a large file size. With Michael's recent work, they
are mostly rendered correctly but with a large size, I think.

This is on my TODO list, but I am not getting to this any time soon so others
please feel free to have a go. A hint would be
http://bugs.ghostscript.com/show_bug.cgi?id=690867#c5
and utilize Michael's linked icc transforms.

BTW, 8.71 seems to have some JPX-related problem and won't read the input file.
The large output file size is with 9.x?
