If you type "console.profile()" into the console of the WebInspector and then "console.profileEnd() the title of the profile will be "undefined". This is because the arguments value in _evalInInspectedWindow in Console.js will pass the empty argument onto the inspected window. In Console::profile in Console.cpp the title argument will be "undefined". I could detect this at Console::profile() and change the title to "org.webkit.profiles.user-initiated" but then if a user ever set the title of their profile to "undefined" they would get this behavior. Which may not be that bad

This is actually correct behavior. If a title isn't supplied it should be "undefined". Firebug simply does not display a title. Maybe we should consider that.
