You are right. You have also reminded me that I actually tried that and 
had the same result. That was when I took the "this + os.path.sep + 
that" road, blindly flailing about bashing my head against the cell walls.

I sometimes think I'll never learn to read the error messages. You could 
never trust them in the eighties. No Python you see!

I'm much happier nowadays :)
