After studying the patch that introduced this, it seems to me that the
one line

  (buffer-disable-undo)

in locate.el:472 was sneaked in without further justification.

Luc, could you test if removing this line solves your problem?  Also,
could you see if the original problem addressed by this patch, i.e.

  Reverting Locate mode buffers (via locate-update) currently ignores
  filters from locate-with-filter.  It also doesn't work with uniquely
  renamed buffers, or when locate has been called non-interactively
  (e.g., from eshell/locate) and locate-history-list and
  locate-grep-history-list aren't modified.

remains solved after removing that line?
