Android Facebook SDK UserSettingsFragment 在完成任务之前暂停时崩溃

Question

我使用 com.facebook.widget.UserSettingsFragment 在我的应用程序中管理登录/注销 Facebook:

UserSettingsFragment userSettingsFragment = new UserSettingsFragment();
Session session = Session.getActiveSession();
if(session==null || session.isClosed()){
    userSettingsFragment.setPublishPermissions(Arrays.asList("publish_actions"));
}
fragmentTransaction.replace(R.id.content_container, userSettingsFragment, "userSettingsFragment");

它似乎可以正确登录/注销，但是当我启动这个 Fragment 时我已经登录并暂停它(例如通过替换 Fragment)，它崩溃。它似乎有一些线程在运行，当它完成时，它需要 Activity 但它不再存在，所以它崩溃了。

我觉得这像是一个错误，还是我遗漏了什么？
