Basically, it comes from a conflict between Unsanity's APE (Application Enhancer, used for FruitMenu, WindowShade, etc.) and XDarwin. Excluding OroborOSX from the applications that are "enhanced" by FruitMenu, WindowShade or any of the Unsanity's PrefPanels restores OroborOSX functionality.
Hope they get this thing fixed soon!
