Hi maintainers,

ido commands that finally calls ``ido-make-buffer-list'' would fail to
execute if there is some killed buffer returned by
``buffer-list''. Because (buffer-name a-killed-buffer) will return nil,
``ido-ignore-item-p'' fail to treat it as a stream. My solution is to
return non-nil if name passed to ``ido-ignore-item-p'' is nil.

The attachment is the patch I made for ido.el.
