[O] Problem with hourly repeater

[Memnon Anon]

Hi, 

I am trying the hourly repeaters and see a problem.

Steps to reproduce:
* "emacs -Q"
* load minimal setup:

--8<---------------cut here---------------start------------->8---
;;; adjust path as needed!
(setq load-path (cons "~/org-mode/lisp" load-path))
(setq load-path (cons "~/org-mode/contrib/lisp" load-path))
(setq load-path (cons "~/org-mode/contrib/babel/lisp" load-path))
(require 'org)
(setq org-clock-persist t)
(org-clock-persistence-insinuate)
(setq org-clock-history-length 50
      org-clock-in-switch-to-state "STRT"
      org-clock-idle-time 5
      org-log-done 'time
      org-log-reschedule 'time
      org-log-into-drawer "LOGBOOK")

(setq org-agenda-files (quote ("~/agenda.org")))
(setq debug-on-error t)
--8<---------------cut here---------------end--------------->8---

* Minimal agenda file ~/agenda.org:

--8<---------------cut here---------------start------------->8---
#+SEQ_TODO: TODO STRT | DONE DEFD CNCL

* TODO Test
  Scheduled: <2012-10-08 Mo 18:00 +6h>
--8<---------------cut here---------------end--------------->8---

* "M-x org-agenda" a ->
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p
nil)
[...]

This is with
Org-mode version 7.9.2 (release_7.9.2-424-g0ccf65 @ 
and 
GNU Emacs 24.2.50.1 (i486-pc-linux-gnu, GTK+ Version 3.4.2) of
2012-10-04 on dex, modified by Debian

Anyone else see this?
