[O] "org-time-stamp" and "org-time-stamp-inactive" no longer work

[York Zhao]

Hi,

I have noticed this problem for awhile and now I think it is worth reporting it
and hopefully get fixed.

Here is what happened when I hit "C-c !" in org buffer:

Debugger entered--Lisp error: (wrong-type-argument window-live-p nil)
  select-window(nil)
  org-eval-in-calendar(nil t)
  byte-code("\306 \210\307\216\310\311!\312 \211\313 8)\314\315!\203!

....

  org-read-date(nil totime nil nil (20194 25121 578000) nil)
  org-time-stamp(nil inactive)
  org-time-stamp-inactive(nil)
  call-interactively(org-time-stamp-inactive nil nil)

Thanks,
