Hi,
I've got a recurrent segmentation fault while playing with several
frame in emacs 24.
I've got several backtraces. All mention `tooltip', but are sometimes
different and segfault later in GTK.
This one seems the most accurate (I got it twice on 4 tries). I can also
provide the other ones if that can help.

(gdb) print f
$1 = (FRAME_PTR) 0x2bd7ee0
(gdb) print f->output_data
$2 = {tty = 0x0, x = 0x0, w32 = 0x0, ns = 0x0, nothing = 0}
(gdb) print f->output_data.x
$3 = (struct x_output *) 0x0
The relevant code seems to be:
648 int
649 xg_hide_tooltip (FRAME_PTR f)
650 {
651 int ret = 0;
652 #ifdef USE_GTK_TOOLTIP
653 if (f->output_data.x->ttip_window)
^^^ here
654 {
655 GtkWindow *win = f->output_data.x->ttip_window;
[…]
670 #endif
671 return ret;
672 }
I've no idea how to "fix" this. Any hint appreciated. I can test patches
if needed.
