segfault when using QtCharts

Hi!

I was running qhot main.qml in my project and everything was going fine until I started to work with QtCharts 2.3:

> qhot main.qml        
qrc:/main.qml:104:5: QML Connections: Implicitly defined onFoo properties in Connections are deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }
[1]    537113 segmentation fault (core dumped)  qhot main.qml

Here is a minimal code example to reproduce the bug:

import QtQuick 2.15
import QtCharts 2.3

Rectangle {
    color: "red"
    ChartView { }
}

Then it runs if I comment out ChartView { }.

Besides that, I can normally run my application binary.

I am using Arch Linux (updated) with the current qt5 package group.

Thanks!

Also hit this issues, both in qhot and my own app. Seems like QtCharts uses QWidgets internally, and thus needs a full QApplication instead of QGuiApplication. Patching qhot to use QApplication and requiring the Widgets component in the CMakeLists works for me.

Could you make a draft/PR with those changes?

@joaoantoniocardoso Not sure if you got a notification for it, but I added a PR.
