1350      xid = *((gulong *)selection_data->data);
(gdb) p *selection_data
$1 = {selection = 0x7a, target = 0x80, type = 0x4f9, format = 137608392, data = 0x0, length = -1, display = 0x80ea098}

2007-04-29  Vincent Untz  <vuntz@gnome.org>

	* libwnck/pager.c: (wnck_pager_drag_data_received): return instead of
	dumbly continuing in this function when we know that the drag doesn't
	work
	Should fix bug #415675
