Qt GraphicWebView Segmentation fault (sigsegv) when loading cesiumJS with Natural earth

I created a Qt widget project and added a webView. On webView I set the url to a localhost and loaded the CesiumJS HelloWorld.html. JUST IT.

When I selected "natural earth" as map, the application has trhow a SIGSEGV error (segmentation fault).

What in Qt can throw this error? how can i avoid this. is there any webView configuration ?


mode details.

This is my Main.qml

import QtQuick 2.5
import QtQuick.Window 2.2
import QtWebEngine 1.1
Window {
    visible: true

    width: 860
    height: 460

       WebEngineView {
           id: webview
           url: "http://localhost:8080/apps/"
           anchors.fill: parent
This is Main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QtWebEngine>

int main(int argc, char *argv)
    QGuiApplication app(argc, argv);
    QQmlApplicationEngine engine;

    return app.exec();
