When I click on my account and click allow for it to use my service, it crashes. I have given a video to show what is happening.

Built from source, it is crashing in the LoginViewController:

            if let index = url.firstIndex(of: "=") {
                let code = String(url[url.index(index, offsetBy: 1)...])
                authenticator.authenticate(code: code) { err in
                    if let err = err {
                        **self.Log.error("Error: \(err)")**
                    } else {
                        self.loadNextScreen()
                    }
                }
            }
            return

Getting the following message:

Apart from LoginViewController, places where related with NSError seems causing an issue some how.
