I appreciate the help, but it has only ever failed on this single image. I just don’t have the time or inclination to debug this in a program that I would have to learn to in fact debug it with any efficiency. If this isn’t failing for anyone else, I’ll just chalk it up as an anomaly for now.
If I run into this again and can’t find a way around, maybe I’ll take up the challenge to debug it. Either way, thanks for the tips!
