Open "emacs -Q" and run the following code:
(let ((ido-enable-dot-prefix t))
(ido-completing-read "Pick: " '("" "a" "b" "c")))
Then try to type anything and you will get a message (but no backtrace):
Error in post-command-hook (ido-exhibit): (args-out-of-range "" 0)
And ido completion will be broken. This happens any time
ido-enable-dot-prefix is non-nil and "" is one of the choices for ido.
The following patch to ido.el seems to fix the problem.
