Incidentally, i see the same thing with gtk+ 2.7.x.

[ disable accelerator in entry's enter-notify ]
[ enable accelerator in entry's leave-notify ]

That assumes you're using the mouse, and will fail if you drive with the
keyboard.  Would be better to use "focus-in-event" and "focus-out-event". 
But, your suspicion is correct, it's just a kludge.

The can-activate-accel trick *should* be working, e.g.,

  $button->signal_connect (can_activate_accel => sub {
        # inhibit the accel by returning TRUE.
        # the signal uses the same boolean-handled-accumulator
        # as events; so returning TRUE from the handler should
        # cause $button->can_activate_accel(...) to return FALSE.
        #
        # don't allow the accelerator to activate if we're typing
        # in the entry.
        return ($window->get_focus == $entry);
  });

but no matter how i do that, even just using "sub {return TRUE}",
$button->can_activate_accel($id) returns TRUE.  Even tried with a small C
program, and am confused by the results.
