I think this is the same as bug#57572 -- it's bugging out here:

               ;; FIXME: This is a sanity check.  When this error
               ;; doesn't happen for a while, it can be removed.
               (or (file-name-absolute-p localname)
                   (tramp-error
                    vec 'file-error "File `%s' must be absolute" localname))

So I guess this sanity check should perhaps be removed?  Michael?
