  May I, as an ordinary user, suggest the attached mini-patch for the pnm-backend
  (for the case it's still included in Sane-1.0.5)?
  The problem:
  If you type in a valid filename like
  /home/bla/testimage.pnm
  and then delete some characters like
  /home/bla/testimage.p
  SANE_INFO_RELOAD_PARAMS isn't set and therefore the frontends can't
  update their displays correctly. The patch (against pnm.c in Sane-1.0.4) ensures
  that SANE_INFO_RELOAD_PARAMS is set whenever the string changes.
