エラー: CursorWrapperInner(10908): 事前の close() なしでカーソルが終了しました

Facebookコードを自分のアプリで動作させようとしています。何らかの理由で、サンプルでもこの​​エラーが発生しますか? 理由はわかりませんが、上記と同じエラーが発生するフラグメントを次に示します。

コード：

package com.fragments;

public class MainDisplayFragment extends Fragment {

    private static final String TAG = "MainFragment";
    private UiLifecycleHelper uiHelper;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.main_display_fragment, container,
                false);

        uiHelper = new UiLifecycleHelper(this.getActivity(), callback);
        uiHelper.onCreate(savedInstanceState);

        // Facebook login button.
        LoginButton authButton = (LoginButton) view
                .findViewById(R.id.authButton);
        authButton.setFragment(this);
        // Set Application ID.
        authButton.setReadPermissions(Arrays.asList("user_friends",
                "user_about_me", "user_birthday", "user_likes", "user_status"));

        return view;
    }

    private void onSessionStateChange(Session session, SessionState state,
            Exception exception) {
        if (state.isOpened()) {
            Log.i(TAG, "Logged in...");
        } else if (state.isClosed()) {
            Log.i(TAG, "Logged out...");
        }
    }

    private Session.StatusCallback callback = new Session.StatusCallback() {
        @Override
        public void call(Session session, SessionState state,
                Exception exception) {
            onSessionStateChange(session, state, exception);
        }
    };

    @Override
    public void onResume() {
        super.onResume();
        uiHelper.onResume();
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        uiHelper.onActivityResult(requestCode, resultCode, data);

    }

    @Override
    public void onPause() {
        super.onPause();
        uiHelper.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        uiHelper.onDestroy();
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        uiHelper.onSaveInstanceState(outState);
    }
}
