[O] [bug] org-agenda view fails if I have missed a deadline

Hello,

with org up to date as of a minute ago, if I try to view my current
agenda, which happens to have an entry that has missed its deadline
(i.e. the deadline is in the past), org fails with an error:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  format(nil 1)
  (cond ((> diff 0) (format future diff)) ((string= future past) (format past 
diff)) (t (format past (abs diff))))
  (let ((future (nth 1 org-agenda-deadline-leaders)) (past (nth 2 
org-agenda-deadline-leaders))) (cond ((> diff 0) (format future diff)) 
((string= future past) (format past diff)) (t (format past (abs diff)))))
  (if (= diff 0) (car org-agenda-deadline-leaders) (let ((future (nth 1 
org-agenda-deadline-leaders)) (past (nth 2 org-agenda-deadline-leaders))) (cond 
((> diff 0) (format future diff)) ((string= future past) (format past diff)) (t 
(format past (abs diff))))))
  (let ((diff (if (< (org-today) current) diff (- deadline current)))) (if (= 
diff 0) (car org-agenda-deadline-leaders) (let ((future (nth 1 
org-agenda-deadline-leaders)) (past (nth 2 org-agenda-deadline-leaders))) (cond 
((> diff 0) (format future diff)) ((string= future past) (format past diff)) (t 
(format past (abs diff)))))))
  (org-agenda-format-item (let ((diff (if (< (org-today) current) diff (- 
deadline current)))) (if (= diff 0) (car org-agenda-deadline-leaders) (let 
((future (nth 1 org-agenda-deadline-leaders)) (past (nth 2 
org-agenda-deadline-leaders))) (cond ((> diff 0) (format future diff)) 
((string= future past) (format past diff)) (t (format past (abs diff))))))) 
head level category tags (and (= diff 0) timestr)) 
--8<---------------cut here---------------end--------------->8---

Changing the deadline in the offending entry allows the agenda to be
shown.

Thanks,
eric
