facebook sdk在应用程序委托中崩溃

Question

这是我复制bug的方法.所以这是我登录的代码:

@IBAction func FBLoginAction(_ sender: AnyObject) {
    fbLoginManager.loginBehavior = FBSDKLoginBehavior.browser
    fbLoginManager.logIn(withReadPermissions: ["public_profile", "email", "user_friends"], from: self) { (result, error) -> Void in
        if (error != nil) {
            return
        }
    }
 }

如果我登录两次,然后再次运行该应用程序,此行将在appdelegate中崩溃.

    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)

如果我只登录一次,然后再次运行应用程序,则不会发生崩溃.崩溃的完整堆栈如下:
