I'm sure he did.  Stefan is telling you that perhaps you run the
string through expand-file-name too early, before massaging it in some
way that gives a valid file name.  Or maybe that you should run
expand-file-name only on parts of the file name, the parts that _are_
valid file names.

`concat' comes to mind.  And if that's not what you want, please
consider describing the problem you are trying to solve.

Call expand-file-name on parts of a file name, then `concat' them
together (with any number of slashes that you want)?
