I tried DEADLINE today. The steps are:
1. C-c C-d to add DEADLINE, choose date from calendar.

2. Try ido-switch-buffer, didn't work and Emacs show
Error in post-command-hook: (void-variable org-ans1)

3. C-h v post-command-hook, Emacs show
post-command-hook\ \ \  is void as a variable.

4. Try ido-switch-buffer, it worked.

So, I use *C-h v post-command-hook* to solve the problem :)

Emacs 23.1 on Ubuntu9.04, Org-mode 6.36.
