This patch is for anonymous cvs.
This fixes following problems.
1. When gtk+ is compiled with --with-xinput feature, and input device is
not powered on, X io error occurs.
2. In my X environment, Shift + Tab produces the keysym XK_ISO_Left_Tab.
Gtk only expects for XK_Tab, so focus does not move backward.
