I had a look at the upstream patch, and it do not apply cleanly to the code in unstable, as the code has been restructured quite a bit upstream. As unshield is currently missing from testing, and today is the last day to upload packages missing in testing, I suspect unshield will be missing from Stretch. At least I lack the capacity to fix the problem in time. -- Happy hacking Petter Reinholdtsen
