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

[danie...@outlook.com]

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 ?

thanks

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);
QtWebEngine::initialize();
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

return app.exec();
}
this error
