Sorry about spamming list and not being helpful instead of putting stuff in bugzilla.
https://bugs.freedesktop.org/show_bug.cgi?id=60383 This has sunk too much of my time today, but hey at least I've learned some stuff along the way. libopenjpeg doesn't support CMYK JPX images, neither does Poppler. I will look into it, but I don't know how far I'll get.
