Android Permission Denial: broadcasting Intent

I really do not know what is wrong, but my if widget is update by system by "APPWIDGET_UPDATE" it throws following exception. I tried several things, exporting receiver (true/false), I tried it on emulators and real phones, but it is same. I added several intent-filters, but it did not work.

11-06 20:10:10.279: W/ActivityManager(61): Permission denied: checkComponentPermission() reqUid=1000
11-06 20:10:10.279: W/ActivityManager(61): Permission Denial: broadcasting Intent { act=android.appwidget.action.APPWIDGET_UPDATE (has extras) } from com.ency.easychange (pid=1196, uid=10034) requires null due to receiver com.android.settings/com.android.settings.widget.SettingsAppWidgetProvider

My AppWidgetProvider is only declared, because I tried to eliminate possibilities, but the exception is throw before ExchangeRateWidgetProvider.onReceive() is called.

public class ExchangeRateWidgetProvider extends AppWidgetProvider {
    public static final String tag = "ExchangeRateWidgetProvider"; 

        @Override
        public void onUpdate(Context context, AppWidgetManager appWidgetManager,
                int[] appWidgetIds) {

        }   
}

My Manifest:
