Add RestEvent to the named music list:

%%%%
% . . .
guitbarre =
#(define-music-function (barre location str music) (string? ly:music?)
   (let ((elts (extract-named-music music '(RestEvent NoteEvent 
EventChord))))
% . . .
%%%%

Or switch out the logic to look for typed music:

%%%%
% . . .
guitbarre =
#(define-music-function (barre location str music) (string? ly:music?)
   (let ((elts (extract-typed-music music '(rhythmic-event))))
% . . .
%%%%
