QML FileDialog memory leak

[blex]

Valgrind detects a memory leak in FileDialog. Is it a problem or just incorrect usage of dialog?

main.cpp:

#include <QApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

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

    return app.exec();
}

main.qml:

import QtQuick 2.4
import QtQuick.Controls 1.3
import QtQuick.Window 2.2
import QtQuick.Dialogs 1.2

ApplicationWindow {
    width: 640
    height: 480
    visible: true
    Button {
        id: button1
        text: qsTr("Press Me 1")
        onClicked: saveFileDialog.visible = true
    }
    FileDialog {
        id: saveFileDialog
        title: qsTr("Please choose a file")
        selectExisting: false
        selectMultiple: false
        nameFilters: [ qsTr("XML files (*.xml)"), qsTr("All files (*)") ]
        onAccepted: {
            console.log(saveFileDialog.fileUrl)
        }
        onRejected: {
            console.log("Cancel")
        }
    }
}

Valgrind output:

136 (16 direct, 120 indirect) bytes in 1 blocks are definitely lost in loss record 10,536 of 11,981

Having the same issue even with simpler HelloWorld application.

main.qml:

import QtQuick 2.3
import QtQuick.Window 2.2

Window {
    visible: true

    MouseArea {
        anchors.fill: parent
        onClicked: {
            Qt.quit();
        }
    }

    Text {
        text: qsTr("Hello World")
        anchors.centerIn: parent
    }
}

Valgrind reports exact the same error as you post.
