I believe this bug in now fixed in the emacs-23 branch, thanks to the
reversal of the patch that changed this behavior (replaced by
a different one which happens not to make this change).

In the version of ido shipped with 23.2, the behaviour of the
ido-make-buffer-list function no longer permits a default value to be
used by ido-read-buffer unless that value is the name of a preexisting
buffer.

This can be reproduced by evaluating:

(ido-read-buffer "Buffer: " "nonexistent-buffer")

In 23.2, you will see only a list of your current buffers. In 23.1,
nonexistent-buffer is the default value.

This prevents ido-everywhere from being useful in situations like C-u M-x
shell; it should, and in 23.1 did, offer a default name
for your new shell (eg, "*shell*<2>"). ido no longer displays that option,
as it is filtered out by ido-make-buffer-list.

I believe the related commit may be:
