"f.QueryInterface is not a function" for malformed URL in webdriver.Firefox().get()

[HelgaOR]

I encountered behavior that seems incorrect. When (by accident) I supplied a malformed URL to get() method (in my case, something like "http://localhost:7070somepage" - note that slash is missing), I got very strange exception:

Traceback (most recent call last):

It seems this kind of situation needs to be handled differently, to give user more relevant information on the problem (something like "MalformedURLException")
