You get a similar problem when you check out a working copy from one
URL, and then try to "svn copy URL LOCALFILE" using an URL that refers
to the same repository by a different name. (At least, I think that's
what I was doing when I encountered a problem.)

Just figure out the UUIDs for both ways of accessing the repository, and
allow the operation if the UUIDs are identical. People who have two
or more different repositories with the same UUID, and who mix up the
different repositories in this way, will lose.
