xemacs 21.5.3 GTK|GNOME annoyance : it goes BEEP when it shouldn't.

with XEmacs 21.5.3 -- from CVS on september 21 -- compiled --with-gnome and --with-gtk, it beeps on errors, despite the following efforts to stop it: configured and compiled: --with-sound=none ran: xset b off disabled "enable sound server startup" in GNOME Control Center evaluated: (setq bell-volume 0) under those conditions -- and, presumably, under any conditions with the GTK gui -- , it also beeps on 'quit', unless debug-on-quit is non-nil this is only when it's running with the gtk gui, not when it's running in a tty it's far from being a release-critical bug. it's just an annoyance, getting a "BEEP" (as opposed to a backtrace) with every C-g , and with every time i try to move the cursor past the end or beginning of the buffer. after 'xset b off' and bell-volume set to 0, (beep) -- and whatever similar of it is being called from (signal foo bar) -- should have no audible effect.
