Description

When I sometimes close my PySide2 5.13.0 application which contains a FileDialog inside an Item inside of a custom QQuickItem, I get a lot of TypeError messages printed to the console. Using my extremly trimmed down example below, the TypeError messages do not display if I nest the FileDialog directly under CustomView or if I use width and height instead of anchors.fill.

main.py:

import sys

from PySide2.QtCore import QUrl
from PySide2.QtQml import QQmlApplicationEngine, qmlRegisterType
from PySide2.QtWidgets import QApplication
from custom_view import CustomView

import qml_rc


if __name__ == "__main__":
    app = QApplication(sys.argv)

    qmlRegisterType(CustomView, "CustomView", 1, 0, "CustomView")
    engine = QQmlApplicationEngine()
    engine.load(QUrl("qrc:/main.qml"))

    if not engine.rootObjects():
        sys.exit(-1)

    sys.exit(app.exec_())

main.qml

import QtQuick.Controls 2.13

ApplicationWindow {
    visible: true

    CustomView {}
}

custom_view.py

from PySide2.QtQuick import QQuickItem


class CustomView(QQuickItem):
    def __init__(self, parent: QQuickItem = None) -> None:
        super().__init__(parent)

CustomView.qml

import QtQuick 2.13
import QtQuick.Dialogs 1.2
import CustomView 1.0

CustomView {
    Item {
        anchors.fill: parent
        FileDialog {}
    }
}

qml.qrc

<RCC>
    <qresource prefix="/">
        <file>CustomView.qml</file>
        <file>main.qml</file>
    </qresource>
</RCC>

The errors I see when closing the application:
