Bug: emacs 23.2 doesn't like ido-completing-read

[Mark Walters]

Hello

I have been experimenting with notmuch-always-prompt-for-sender on my
debian stable setup (emacs 23.2.1) and it doesn't like
ido-completing-read. It goes to the minibuffer and then it seems to be
impossible to exit the minibuffer.

I can find an emacs bug report #3274 and some discussion
http://comments.gmane.org/gmane.emacs.bugs/27856 which indicates that it
is a problem with ido initialisation. Unfortunately I can't get from there to a
solution (except upgrade emacs).

Many thanks

Mark
