Thanx man, it works now! My main error was to use a HeaderContributor without a scope class. So I did just like you: I now use a theme class which sets itself as a scope.
BUT it wasn't enough, because the previous HeaderContributors kept sticking into my page. But keeping a reference to them now allows me to perform a remove(previousHeaderContributor), which just works fine. Thanks everybody, problem solved!
