If a URL with and invalid scheme is requested after the network connection has been closed the browser will not reconnect, attempt to load the URL or give any indication that the URL entered is invalid. To Reproduce: Launch the browser with the keyboard open Terminate the network connection Return to the browser and enter a URL with invalid scheme (eg. httq://www.yahoo.com) Select the Go button Note that while a status bar moves through the URL entry field, no connection is made, no attempt is made to load the URL and no indication is given that the URL is invalid.
This doesn't sound like a WebKit bug.
