iOS - Validation fails due to code signing in Xcode 4.2 developer preview 6?

Question

Not sure what's going on, but with dev preview 6, I get the following warning: Application failed codesign verification. The signature was invalid, or it was not signed with an iPhone Distribution Certificate. (-19011)

Now I know you can't/shouldn't submit with dev previews and beta SDKs, however, before dev preview 6 (which is when this happened), it would successfully validate. I've definitely picked the correct certificate; it's been used for previous version of my app and it won't expire.

Is this just a dev preview "quirk" that will hopefully go away for the proper release? I just want to make sure my update is ready to be submitted on day one of release.

Anyone else come across this?

Try restarting Xcode and your computer. Delete and reinstall the distribution certificate. Make sure your bundle identifier definitely matches up. If all that fails, try creating a new certificate, that won't kill you. If it still doesn't work, look this up in Google. I remember having this problem and there were a lot of interesting solutions I found.
