[background]: gnome-control-center crashed with SIGSEGV in type_node_check_conformities_UorL()

[Scott Thatcher]

This crash happened when selecting the "Brightness and Lock" icon in system settings. Had similar crashes changing desktop background and doing other things related to system settings. Expected normal system settings options, got a crash that killed system settings. Seems similar to a bug that's marked "fix released" so I thought I should submit it again, since it doesn't seem fixed. Thanks for your work on Ubuntu.
