That was not the only bug introduced by the following change:

    2006-09-09  Matt Hodges  <address@hidden>

        * locate.el (locate-current-search): New variable.
        (locate): Set buffer local value.  Use current buffer if it is
        in Locate mode.
        (locate-mode): Disable undo here.
        (locate-do-setup): Use locate-current-filter from buffer to be killed.
        (locate-update): Use locate-current-search and locate-current-filter.

Undo no longer works in a locate buffer.  This is a serious bug and a
regression in Emacs 22 if it does not get fixed.  You are supposed to
be able to do essentially everything you can do in a dired buffer
(including undo) in a locate buffer.  That is the very purpose of
locate-mode.

>From the above changelog entry, this bug seems to have been introduced
_on purpose_.  What was the purpose of the above changes?  They seem to
have been made by somebody who does not understand how other people
use locate mode and only cares about the way he personally uses it.
Who knows what else these changes broke.

Sincerely,

Luc Teirlinck.
