This is what I get.  It looks slightly different from yours.

  tramp-file-name-structure's value is 
  ("\\`/r\\(@\\([a-z0-9]+\\)\\)?:\\(\\([-a-z0-9_#]+\\)@\\)?\\([-a-z0-9.]+\\):\\(.*\\)\\'" 2 4 5 6)


  *List of five elements (REGEXP METHOD USER HOST FILE), detailing the tramp file name structure.

  The first element REGEXP is a regular expression matching a tramp file
  name.  The regex should contain parentheses around the method name,
  the user name, the host name, and the file name parts.

  The second element METHOD is a number, saying which pair of
  parentheses matches the method name.  The third element USER is
  similar, but for the user name.  The fourth element HOST is similar,
  but for the host name.  The fifth element FILE is for the file name.
  These numbers are passed directly to `match-string', which see.  That
  means the opening parentheses are counted to identify the pair.

  See also `tramp-file-name-regexp' and `tramp-make-tramp-file-format'.

  You can customize this variable.

  Defined in `tramp'.


M-x tramp-version returns this.

It ends up with the same error as this.
