Android InstantiationException с фрагментом (он открыт)

У меня есть Fragment (это не внутренний класс, и он не имеет никакого конструктора)

public class PreferenceListFragment extends ListFragment implements OnClickListener

Я получаю этот отчет о сбоях в консоли разработчика Android:

java.lang.RuntimeException: Unable to start activity

Я не могу воспроизвести это на любом из моих тестовых устройств.

Здесь PreferenceActivity.onCreate, где происходит исключение:

public class PreferenceActivity extends FragmentActivity{

    PreferenceListFragment frag;

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);

        setContentView(R.layout.preference);

        frag = (PreferenceListFragment) getSupportFragmentManager().
                findFragmentById(R.id.preference_list_frag);
        frag.setState(AlarmPreferenceState.Selected);
        frag.setIsTwoPane(false);
    }

    .
    .
    .
}

И вот R.layout.preference:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <fragment class="com.redacted.redacted.PreferenceListFragment"
          android:id="@+id/preference_list_frag"
          android:layout_width="match_parent"
          android:layout_height="match_parent"/>

</FrameLayout>

Кто-нибудь знает, почему я могу получить это исключение и/или как его воспроизвести?
