Actively maintained distros using the GTK+-2.18 branch would have picked up the fix there. But distros on the GTK+-2.16 branch are unlikely to have backported the patch (Ubuntu 9.04 and Fedora 11 haven't), so applying the workaround to 1.9.1 would help people.
The patch only adds null checks in places where null values would cause a crash.
