You have a pirated app on your Mac. You have downloaded a free app somewhere instead of buying it from the Mac App Store. The free app has been cracked with the MAS receipt from the Angry Birds app obtained from this other person's account. Get rid of the pirated app and the issue will go away.'09 Mac mini, '06 iMac, iPad 2, Mac OS X (10.7), iOS (4.3.5) Mac fanboy since 1984!

I've had just the same problem and is almost impossible to solve it. I've tried everything but just as you say it's an incredibly complicated issue. In my case I can't even locate the file of the app. Just as if it doesn't existed.
