Never had a shutter problem with a rangefinder before...unless I left the lens cap on and that's happened more times than one. The only other time I've gotten nothing on negatives was when I inadvertently poured in the fixer first. You won't do that but once. I labeled every container after that little episode back in the early days. If any image at all appears, as you show, I hope it's an easy fix on the shutter.
