I added my Gmail address book to Evolution, but it gives me an error every time, even when choosing "use secure connection" in the address book options. The error is (I translated it on my own):
unable to open address book. This is because you entered a wrong URI or the server is unavailable at the moment. Details: cannot open book: source already loaded!
Sometimes, when I click the button 'reject error', it does load the address book but when I return to Evolution after a while, it gives me the same error and sometimes I cannot load the address book. This is very annoying since I have to use Evolution a lot.
