Hi all,

The following snippet inserts a button with a long label and a wrap-prefix.  Clicking the prefix causes an error, whose backtrace is shown below.

(with-current-buffer (get-buffer-create "*button*")
  (erase-buffer)
  (insert-text-button
   (let ((str "long long long long text "))
     (concat str str str str str))
   'follow-link t
   'action (lambda (&rest args) (print args))
   'wrap-prefix "this is the wrap prefix")
  (pop-to-buffer (current-buffer)))

Debugger entered--Lisp error: (void-function nil)
  nil(("this is the wrap prefix" . 9))
  button-activate(("this is the wrap prefix" . 9) t)
  push-button((mouse-2 (#<window 13 on *button*> 81 (76 . 29) 379842354 ("this is the wrap prefix" . 9) 81 (9 . 1) nil (4 . 12) (8 . 17))))
  funcall-interactively(push-button (mouse-2 (#<window 13 on *button*> 81 (76 . 29) 379842354 ("this is the wrap prefix" . 9) 81 (9 . 1) nil (4 . 12) (8 . 17))))
  call-interactively(push-button nil nil)
  command-execute(push-button)

Cheers,
Clément.
