That's similar to what i originally thought. I thought it must
be a bug that a NULL ever made it to check_path. But i looked in
repos_to_repos_copy, and it treats NULL as if it is a perfectly
reasonable value to have (by doing some manipulation on the path
if it isn't NULL and not signalling an error if it is). I also
looked at ra_dav's check_path and see that it also treats NULL as
acceptable. Based on that evidence i concluded that it is legal
to pass a NULL to check_path.

If that is deemed incorrect, i can provide a patch fixing all
check_path callers.
