Yes Chris, that would be a good test of the camera's light seal. You could also shine a bright torch/flashlight around the edges of the door to produce the same result.

You can lay the negative strip you scanned in the camera, line up the exposed fames with the imaging area (image upside down, emulsion down of course!), and you should find your light leak about half a frame away from the imaging area. I think your problem lies at the base of the camera, between the imaging area and the unexposed film-feeding spool. The feed spool might account for the straight edge on the fogged area, which would place the leak right against the feed spool. This would explain why it's only occurring at the end of the film; the bulk of the film will block the leak until it's almost used up.
The other thing that could account for the straight line is the roller at the edge of the imaging area, but I don't think the leak is there as it's too far from the edge of the frames.
Update: According to this website, http://www.butkus.org/chinon/rollei/...eiflex_28e.htm , the second image down shows a roller between the feed spool and the imaging area. I now suspect it's this that is causing that straight line on the flare. That roller isn't on my Yashica.
The reason I don't think it's a post-exposure problem is that the pattern is regular, occurring at the same place on each frame and on the unexposed end frame. Processing fogging, or that from loosely-wound film and torn paper backing, usually occurs much more randomly.
I hope you manage to track down the problem. Have fun with your lovely camera. :-)
