Hello,

On the latest `org-plus-contrib' build from the org package.el repo, my
Agenda buffers (for any Agenda command) fail to render properly, with
these pertinent lines from *Backtrace*:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
  put-text-property(28484 nil org-appt-warntime "60")
  org-refresh-properties("APPT_WARNTIME" org-appt-warntime)
  (or (memq (quote appt) org-agenda-ignore-drawer-properties) (org-refresh-properties "APPT_WARNTIME" (quote org-appt-warntime)))
--8<---------------cut here---------------end--------------->8---

I first attempted to deactivate all use of the appt library in my Emacs,
including my setting of agenda-mode-hook which previously had called
`org-agenda-to-appt'. Still the Agenda would not render correctly.

I then isolated this to the following lines of function
`org-agenda-prepare-buffers':

--8<---------------cut here---------------start------------->8---
	    (or (memq 'appt org-agenda-ignore-drawer-properties)
	        (org-refresh-properties "APPT_WARNTIME" 'org-appt-warntime))
--8<---------------cut here---------------end--------------->8---

With these lines commented out, my Agenda buffer was able to load
correctly.

Best,
WGG
