[Message part 1 (text/plain, inline)]

emacs -Q

Then I evaluate the following:

(require 'ido)
(ido-mode)
(ido-everywhere 1)
(setq ido-work-directory-list
'("/home/fenton/projects/docs-DIR/documentation"
"/home/fenton/projects/python/thai_real_estate/tre/"))

Then I do a C-x C-f and type in the letters 'for'

Then the minibuffer remains empty and unable to enter text in it and the
CPU gets pegged to 100%.  Waiting doesn't resolve it.

I can't reproduce this.

Could you try M-x toggle-debug-on-quit, follow your recipe to get ido
stuck, and then C-g to see the backtrace?

More information was requested, but no response was given within a few
months, so I'm closing this bug report.  If the problem still exists,
please reopen this bug report.
