Indeed it looks like maybe you just lost the last bit of the film emulsion cutting off the bottom of the last frame (which is the top of the last image). I donít know anything about malfunctioning backs and what they produce but I agree it would be odd with a light leak to get only one frame affected. Iíd say itís just how you set up the magazine insert.

Seems a lot depends on whether it really is at the end of the roll. If it is, I believe Richard has nailed it. Nick, is that "false chromatic line" all the way to the end of the film? I'm puzzled because that area doesn't look evenly spaced from the top of the frame in your picture. If it's the end of the film, it ought to be. Still, the wide frame spacing really does suggest you ran out of film.
May the light be with you.
