[The remaining 3/4 of the message seems to demand that the question be destroyed unread. I'll live dangerously; I'm a rebel.]

It's nothing to do with you; ignore it. Apparently it's internal to the Lion window manager's support of Mission Control, Versions, and the like. It doesn't even matter that you don't use those things.

If you look through the Console, you'll find a distressing number of Apple-internal messages calling out persistent failures in their software, with no effect on the correct functioning of the machine.

It's harmless.
