looking at the source, there is supposed to be some button:

,----
| (defun notmuch-show-insert-part-multipart/signed (msg part content-type nth depth button)
|   (button-put button 'face 'notmuch-crypto-part-header)
|   ;; add signature status button if sigstatus provided
|   (if (plist-member part :sigstatus)
|       (let* ((from (notmuch-show-get-header :From msg))
| 	     (sigstatus (car (plist-get part :sigstatus))))
| 	(notmuch-crypto-insert-sigstatus-button sigstatus from))
|     ;; if we're not adding sigstatus, tell the user how they can get it
|     (button-put button 'help-echo "Set notmuch-crypto-process-mime to process cryptographic MIME parts."))
