"Creating precompiled collator because collator is out of date"

Question

I am trying to "self-destruct" a view controller by doing [[self navigationController] popViewControllerAnimated:YES].

Before I do this, I also present an UIAlertView.

The first time I do this, I get a console-error that says:
WARNING! Creating precompiled collator because collator is out of date. This is expensive!

What does that mean? How can I fix it?

Thank you.

This was simply due to a framework-error in the iOS 4.2.1 beta. I'm not getting this error anymore.
