I have installed Angry birds from the official android market. I tried installing the Angry Birds Seasons free version today, and while installing I got a pop-up message saying "Duplicate provider" and the installation terminated. I am running ICS on Nexus S, if it's relevant.
That means something's wrong with the package setup. For your reference, here are a few links with more detailed information:
Recommendation: Contact developer (for security reasons both developers, in case somebody faked the signature). It's most likely a copy-and-paste error during the packaging process, so the developer might release a fixed update soon.
I think uninstalling Angry Birds and then reinstalling it should fix the problem.
