Rather than searching for the bug, let us try again (I also modified the 
set-image-size function so that it preserves the aspect ratio):


(define (image? t) (tree-is? t 'image))

(define (find-image t)
  (car (tree-search (tree-outer t) image?)))

(define (set-image-size t)
  (tree-set! t 1 (string->tree "0.5par"))
  (tree-set! t 2 (string->tree ""))) ; set to one's wishes


(kbd-map ("v v v" (let ((t (find-image (cursor-tree))))
                   (set-image-size t))))


Let's see if this works :-)
