When trying to execute the code contained in the attachment main.qml on Qt 5.5.0 or 5.5.1 : app automatically crashes.

On Qt 5.4.2 everything works at expected.

NOTE : With a GridView instead of a [Flow|Row|Column]/Repeater everything works perfectly.

main.qml :

main.qml

import QtQuick 2.4
import QtQuick.Window 2.0
import QtQml.Models 2.1

Window {
    visible: true
    width: 640
    height: 480

    ListModel {
        id: myModel
        ListElement { display: "One" ; category: "1" }
        ListElement { display: "Two" ; category: "1" }
        ListElement { display: "Three" ; category: "1" }
    }

    DelegateModel {
        id: visualModel
        delegate: Package {
            Text { id: listDelegate; Package.name: 'list' }
            Text { id: flowDelegate; Package.name: 'flow' }
        }
        model: myModel
    }

    ListView {
        id: lv
        width: parent.width
        model: visualModel.parts.list
    }

    Flow {
        width: parent.width
        height: 50

        Repeater {
           model: visualModel.parts.flow
        }
    }
