Hi,

I get the same bug when selecting a date by mouse. It seems that
org-read-date-display is added to post-command-hook and never
deleted. The code responsible for this seems to be:

	    (unwind-protect
		(progn
		  (use-local-map map)
		  (add-hook 'post-command-hook 'org-read-date-display)
		  (setq org-ans0 (read-string prompt default-input
					      'org-read-date-history nil))
		  ;; org-ans0: from prompt
		  ;; org-ans1: from mouse click
		  ;; org-ans2: from calendar motion
		  (setq ans (concat org-ans0 " " (or org-ans1 org-ans2))))
	      (remove-hook 'post-command-hook 'org-read-date-display)

After the bug happens, every command causes the error (void-variable
org-ans1). post-command-hook looks like:

post-command-hook is a variable defined in `C source code'.
Its value is nil
Local in buffer *followup to Carsten Dominik on gmane.emacs.orgmode*;
global value is

(global-font-lock-mode-check-buffers
global-highlight-parentheses-mode-check-buffers
autopair-global-mode-check-buffers org-read-date-display)

(it is locally set to nil by emacs after an error is triggered, see the
help page of post-command-hook)
