Xcode iOS organizer submit to app store yields “The archive is invalid” error

Question

I just switched from Xcode 3 to 4. When I attempt to upload an app that I have archived to the organizer, I receive this error:

The archive is invalid

Answer 1

In my case this has nothing to do with Xcode or the unix tools. Indeed I happend to had too many distribution certificates (Why? I don't know). Deleted all of them but one, code sign with this one, re code sign it while validating and submit it with no errors. I hop this help.
