QML ChartView: Crash on object destruction when assigend "series" has set an "id"

When I delete a QML Object that contains a ChartView, everything works fine. The moment when I assign the "series" of the chart an ID, the destruction crashes.

Works fine:

import QtQuick 2.7
import QtQuick.Controls 2.2
import QtCharts 2.2

ApplicationWindow {
    visible: true
    width: 640
    height: 480

    ChartView {
        width: 450
        height: 450

        PieSeries {
            PieSlice { label: "eaten"; value: 94.9 }
            PieSlice { label: "not yet eaten"; value: 5.1 }
        }
    }
}

Crashes (see "id: testId in PieSeries):

import QtQuick 2.7
import QtQuick.Controls 2.2
import QtCharts 2.2

ApplicationWindow {
    visible: true
    width: 640
    height: 480

    ChartView {

        width: 450
        height: 450

        PieSeries {
            id: testId
            PieSlice { label: "eaten"; value: 94.9 }
            PieSlice { label: "not yet eaten"; value: 5.1 }
        }
    }
}

just start/quit the program, and it will not exit correctly due to the crash on destruction. This happens with any ChartView / Series combination.
