I notice the same error with gtkairo when trying to output a non ascii
character to a pane so that's probably what gsharp is trying to
do. The following code should trigger it:

(define-application-frame test ()
  ()
  (:panes
   (app :application
        :display-function (lambda (frame pane)
                            (write-char #\LATIN_SMALL_LETTER_O_WITH_DIAERESIS
                                        pane))))
  (:layouts
   (default (vertically ()
              app))))

(run-frame-top-level (make-application-frame 'test))
