[Nexus 4 Themes and Apps] :
the problem is here

<LinearLayout android:orientation="horizontal" android:id="@id/status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingStart="6.0dip" android:paddingEnd="6.0dip">
[COLOR="Red"][B]<include android:id="@id/signal_cluster" android:layout_marginTop="4dp" android:layout_width="wrap_content" android:layout_height="wrap_content" layout="@layout/signal_cluster_view" />[/B][/COLOR]
<LinearLayout android:orientation="horizontal" android:id="@id/notification_icon_area" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0">
<com.android.systemui.statusbar.StatusBarIconView android:id="@id/moreIcon" android:visibility="gone" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:src="@drawable/stat_notify_more" />
<com.android.systemui.statusbar.phone.IconMerger android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/notificationIcons" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentStart="true" />
</LinearLayout>
<LinearLayout android:orientation="horizontal" android:id="@id/system_icon_area" android:layout_width="wrap_content" android:layout_height="fill_parent">
<LinearLayout android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/statusIcons" android:layout_width="wrap_content" android:layout_height="fill_parent" />
<LinearLayout android:gravity="center" android:orientation="horizontal" android:id="@id/signal_battery_cluster" android:layout_width="wrap_content" android:layout_height="fill_parent" android:paddingStart="2.0dip">

<com.android.systemui.DockBatteryMeterView android:id="@id/dock_battery" android:visibility="gone" android:layout_width="@dimen/status_bar_battery_width" android:layout_height="@dimen/status_bar_battery_height" android:layout_marginBottom="@dimen/status_bar_battery_bottom_padding" android:layout_marginStart="4.0dip" />

</LinearLayout>
</LinearLayout>

it should be like this:

<LinearLayout android:orientation="horizontal" android:id="@id/status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingStart="6.0dip" android:paddingEnd="6.0dip">
[COLOR="red"][B]<include android:id="@id/signal_cluster" android:layout_marginTop="4dp" android:layout_width="wrap_content" android:layout_height="wrap_content" layout="@layout/signal_cluster_view" />[/B][/COLOR]
<LinearLayout android:orientation="horizontal" android:id="@id/notification_icon_area" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0">
<com.android.systemui.statusbar.StatusBarIconView android:id="@id/moreIcon" android:visibility="gone" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:src="@drawable/stat_notify_more" />
<com.android.systemui.statusbar.phone.IconMerger android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/notificationIcons" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentStart="true" />
</LinearLayout>
<LinearLayout android:orientation="horizontal" android:id="@id/system_icon_area" android:layout_width="wrap_content" android:layout_height="fill_parent">
<LinearLayout android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/statusIcons" android:layout_width="wrap_content" android:layout_height="fill_parent" />
<LinearLayout android:gravity="center" android:orientation="horizontal" android:id="@id/signal_battery_cluster" android:layout_width="wrap_content" android:layout_height="fill_parent" android:paddingStart="2.0dip">
<com.android.systemui.BatteryMeterView android:id="@id/battery" android:layout_width="@dimen/status_bar_battery_width" android:layout_height="@dimen/status_bar_battery_height" android:layout_marginBottom="@dimen/status_bar_battery_bottom_padding" android:layout_marginStart="4.0dip" />
<com.android.systemui.DockBatteryMeterView android:id="@id/dock_battery" android:visibility="gone" android:layout_width="@dimen/status_bar_battery_width" android:layout_height="@dimen/status_bar_battery_height" android:layout_marginBottom="@dimen/status_bar_battery_bottom_padding" android:layout_marginStart="4.0dip" />
</LinearLayout>
<com.android.systemui.statusbar.policy.Clock android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="start|center" android:id="@id/clock" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" android:paddingStart="6.0dip" />
</LinearLayout>
</LinearLayout>
