Is URL submission via bookmarklet broken?

http://news.ycombinator.com/submitlink?u=http%3A%2F%2Fbrockerhoff.net%2Fbb%2Fviewtopic.php%3Fp%3D2417%232417&t=Solipsism%20Gradient The title keeps going into the URL field, and then when I submit, I keep getting redirected to news.ycombinator.com/mismatch, with the message: "Dead link: users don't match." Submission via http://news.ycombinator.com/submit works fine.
