No. It is the same race condition as with icomplete.

The recipe is quite similar to what Juanma did:

1. emacs -Q

2. (require 'ido)
   (ido-mode t)
   (setq ido-enable-flex-matching t
         ido-max-directory-size 100000)

[I suppose the last options are not strictly necessary, but maybe it
 helps triggering the bug more frequently]

3. C-x C-f

4. type some random characters until there are no possible completions
of file names in the current directory (ido will start to
search for completions in other dirs)

5. as soon as the message "Searching for `whateveryoutyped`..."
appears, hit <backspace>.

6. go to step 4.

I can trigger the bug after at most 10 repetitions.
