Indeed, it looks like we have a problem in
tramp-find-foreign-file-name-handler: first tramp-tramp-file-p says that
`filename' is a Tramp file, and then tramp-dissect-file-name stabs us in
the back with an error "Not a Tramp file name:".

   (defun tramp-find-foreign-file-name-handler (filename)
     "Return foreign file name handler if exists."
     (when (and (stringp filename) (tramp-tramp-file-p filename))
       (let ((v (tramp-dissect-file-name filename t))

Either the two functions need to be make mutually consistent, or we need
some `ignore-errors' around this function.
Michael, can you DTRT?
