Hi, Nick, the error is not consistent, and I cannot always capture it. 
Is it related to the variable org-ans1?

 From my local buffer (I am *not* very sure whether the value is before 
the error, since sometimes C-h v affect the error conditions and make 
ido-switch-buffer work, I will try to investigate the error when I can 
reproduce it):

;;;
post-command-hook is a variable defined in `C source code'.
Its value is
(linum-update-current t flyspell-post-command-hook)

Local in buffer emacs.org; global value is
(global-font-lock-mode-check-buffers 
global-auto-composition-mode-check-buffers 
global-linum-mode-check-buffers cua--post-command-handler)
