I've seen this when browser testing across Firefox, IE, Chrome, and Safari. Most often it tends to happen with WebKit browsers. Ensure that none of the extensions you're using have PHP errors in them that might effect the headers, especially custom written ones. This will then make that go away. Sorry, wish I could be more specific but without knowing what extensions you're running, it's impossible to tell. If it's no extensions at all, then there is a problem with your environment and, that, I do not know the answer to. Sorry.
