What is the definition of a single bundle application in XCode?

I get this error when I try to validate my iPad app archive that I have build with XCode 4:

“TVGuidePlusHD” does not contain a single–bundle application or contains multiple products. Please select another archive, or adjust your scheme to create a single–bundle application.

I know about the "Skip install" setting, but still it fails for me. The contents of the archive are these:

So is the problem the tvguide.db file? This is my .sql d开发者_如何学编程ocument which is compiled automatically to a sqlite db file and actually is supposed to be copied to the application bundle only.

I'll answer my own question.

After making sure that the tvguide.db file is not inside the "Applications" folder, then the archive is considered a single-bundle application and is validated correctly.
