When I go to www.google.com, and I click on the address box of the browser (either on GtkLauncher and Epiphany), I see two carets, one on the text box of Google's page, and the other one on the address box. The one of the Google's page should not be showing as it doesn't have the focus. I'm using Ubuntu (devel branch Intrepid) with Gtk version 2.12.9, but I've been seeing this bug always.
Fixed in r34125.
