this is:
Atom xcm_selection_atom = gdk_x11_atom_to_xatom_for_display
(screen_x11->display,
screen_x11->cm_selection_atom);
and screen_x11 is NULL. It might be worth printing *event, too.

eww. gdk_event_translate() is a freaking monster...
the relevant code seems to be:
window = NULL;
[...]
get_real_window (display, xevent, &xwindow, &filter_xwindow);
window = gdk_window_lookup_for_display (display, xwindow);
[...]
if (window && !GDK_IS_WINDOW (window))
window = NULL;
[...]
if (window)
{
screen = GDK_WINDOW_SCREEN (window);
screen_x11 = GDK_SCREEN_X11 (screen);
toplevel = _gdk_x11_window_get_toplevel (window);
}
[...]
if (xevent->type - display_x11->xfixes_event_base ==
XFixesSelectionNotify) {
XFixesSelectionNotifyEvent *selection_notify =
(XFixesSelectionNotifyEvent *)xevent;
_gdk_x11_screen_process_owner_change (screen, xevent);
and we crash here with a NULL screen. No clue why the libXi bump gets
gtk confused over a fixes event... cc:ing the gtk maintainers.
According to your xtrace dump the event is something like
000:>:00df: Event XFIXES SelectionNotify(116) subtype=set owner(0x00)
window=0x00600001 owner=0x00000000 selection=0x1("PRIMARY")
timestamp=0xe9facbed selectionTimestamp=0xe9facbed
One thing you might be able to do is try to spot a difference in xtrace
dumps between the working and broken cases?
