I created a node but did not vote on it (i.e. no fivestar rating at all)
I created a view which provided a page with a list view of my poll nodes. I added a "VotingAPI percent vote result" to the list. I selected "Fivestar rating" from the handler.
When I accessed my page view, there was nothing in the in the fivestar field, as in the field was empty. Not until I voted at least once does anything show up.
I think there should definitely be something, some empty starts or the words "no votes yet" displayed if there are no votes, otherwise, it looks like an error in the website.
