[Leica] CL with Light Leak

Yes, that could be. I was looking inside the shutter curtain 'rails' and
they are not totally straight. 
I was looking at my slides and the area of everexposure is as follows:

+----------+
|          |
|    x     |
|    x     |
|    x     |
+----------+

So this area appears at the bottom and goes up, nearly in the middle of
the frame, but not always, and not all the time. Maybe it runs top to
bottom instead of bottom-up (got confused).
Thanks for suggestions, I'll have it looked at, probably after I get the
M6. I already had the rangefinder fixed when I received it through the
mail; too bad it had all these extra problems (meter is not linear
across shutter speeds, frame counter not working as it should be.) Of
course, the seller never saw this.
