For patches it's more important to get the pull request submitted than a trac ticket.
Is this functionality not covered by unit tests? For core patches we're trying to get as much covered as possible (plus it's good practise) so if you could knock up a quick test, check that it fails without your patch and that it passes post patch (without breaking anything else) it will make the process of pulling your changes much quicker.
