Preferences Pane Problem.

I'm wondering if anyone else is having problems with their PrefPanes, specifically "Desktop and Screen Saver", "Spotlight" and "Energy Saver". I am building a Leopard image and didn't notice the problem until I tried going into the "Energy Saver" pane to check if my pmset was working. It gives me a "Could not load (insert perf name) preference pane" error each time I start either of those three. I ran InstaDMG without any updates and it works just fine. But when I include Apple Updates with it then I get the errors. At this point I also have left out my custom packages. I'm in the process of trying to narrow down which update is making it not happy. Anyone already run into this problem?
