Hmm, in fact, is this, from nsterm.m, the culprit?

    case GLYPHLESS_GLYPH:
      if (s->for_overlaps || (s->cmp_from > 0
			      && ! s->first_glyph->u.cmp.automatic))
        s->background_filled_p = 1;
      else
        ns_maybe_dumpglyphs_background
          (s, s->first_glyph->type == COMPOSITE_GLYPH);
      /* ... */
      /* Not yet implemented.  */
      /* ... */
      break;
