Xcode 4.0 crashes when I try to "Validate" or "Submit" via Organizer

Have you ever seen this problem?

When I click on "Validate" in Organizer, I get the following error: "Xcode encountered an internal logic error. Choose "Continue" to continue running Xcode in an inconsistent state. Choose "Crash" to halt Xcode and file a bug with Crash Reporter. Choosing "Crash" will result in the loss of all unsaved data." and Xcode crashes.

Under details it says:

Am I doing something wrong?
I cleared the Cashe, restarted my Mac, and still getting the same error.
What should I do?
Thanks,

 

Thanks for your reply,

Nothing else indicates any problems, build goes well, no errors, no messages, works on simulator.

The problem only occurs when I try to "Validate" or "submit".

I'm downloading 4.0.1 now (have 4.0 now), hoping that will fix the problem.
