Android PreferenceFragmentCompat crashing on ListPreference view

Struggling with getting a PreferenceFragmentCompat to show a ListPreference. I believe I have all the proper things set up. String Arrays

<string-array name="categories">
    <item>Popular Movies</item>
    <item>Top Rated Movies</item>
</string-array>
<string-array name="categories_value">
    <item>popular</item>
    <item>top_rated</item>
</string-array>

Preferences

<?xml version="1.0" encoding="utf-8"?>

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:title="SABRE Settings"
>
<PreferenceCategory android:title="Map Settings"
    >

    <ListPreference
        android:defaultValue="popular"
        android:entries="@array/categories"
        android:entryValues="@array/categories_value"
        android:summary="Select categories of movies"
        android:title="Categories"
        android:key="@string/movies_categories_key" />

</PreferenceCategory>

</PreferenceScreen>

Strings

<string name="movies_categories_key">categoriesKey</string>
<string name="default_movies_categories">popular</string>

Activity Styling

    <style name="Dark" parent="@android:style/Theme.Holo.Light">
        <item name="android:windowBackground">@color/dark_back</item>
        <item name="android:colorBackground">@color/dark_back</item>
        <item name="preferenceTheme">@style/PreferenceThemeOverlay.v14.Material</item>
    </style>

Dependencies

compile ('com.android.support:appcompat-v7:23.4.0')
compile ('com.android.support:preference-v7:23.4.0')
compile ('com.android.support:preference-v14:23.4.0')
compile ('com.android.support:support-v4:23.4.0')

Fragment code

import android.content.SharedPreferences;
import android.os.Bundle;
import android.support.v7.preference.PreferenceFragmentCompat;  
import android.support.v7.preference.PreferenceManager;
import android.view.View;
import com.trt.pst.R;

public class SettingsFragment extends PreferenceFragmentCompat  {


@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    PreferenceManager.setDefaultValues(getActivity(), R.xml.preferences, false);
}

@Override
public void onCreatePreferences(Bundle bundle, String s) {

    addPreferencesFromResource(R.xml.preferences);
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {

    super.onViewCreated(view, savedInstanceState);
    view.setBackgroundColor(getResources().getColor(R.color.background_material_light));
}

}

Fragment deployment

getSupportFragmentManager().beginTransaction()
                    .replace(R.id.single_pane, new SettingsFragment(), "Settings").addToBackStack("RADIO").commit();

The Preferences dialog comes up OK but on pressing to get the expected ListView I get

Does anyone know what I have done wrong to make this happen?
