Thanks.  Could you expand on this?  With gjs-1.30.0, the following
segfaults without any other message:

  var target1 = Gtk.TargetEntry.new("text/plain", 0, 0);
  var target2 = Gtk.TargetEntry.new("STRING", 0, 0);
  var targets = Gtk.TargetList.new([target1, target2]);

The following (with only one target) doesn't segfault until you hit
Gtk.Widget.drag_dest_set(), when it segfaults without any other message:

  var target1 = Gtk.TargetEntry.new("text/plain", 0, 0);
  var targets = Gtk.TargetList.new([target1]);
  drop_box.drag_dest_set(Gtk.DestDefaults.ALL,
                         targets,
                         targets.length,
                         Gdk.DragAction.COPY);

'drop_box' here is a Gtk.EventBox.
