Comment 6 for bug 1226441

This problem is caused by default wallpaper name change in ubuntukylin-default-settings. We change it from "ubuntukylin-default-settings.jpg" to "warty-final-ubuntukylin.jpg" according to name rules. But in ubiquity-dm of ubiquity it search the wallpaper by "ubuntukylin-default-settings.jpg". The codes are showed as following:

            for background in (
                    '/usr/share/backgrounds/edubuntu_default.png',
                    '/usr/share/xfce4/backdrops/ubuntustudio-1310.png',
                    '/usr/share/xfce4/backdrops/xubuntu-wallpaper.png',
                    '/usr/share/lubuntu/wallpapers/'
                    'lubuntu-default-wallpaper.png',
                    '/usr/share/backgrounds/ubuntukylin-default-settings.jpg',
                    '/usr/share/backgrounds/warty-final-ubuntu.png',
                    '/usr/share/backgrounds/gnome/FootFall.png'):
