Qt Quick apps crash when ComboBox is given a model

Qt Quick apps crash when a ComboxBox object is given a model.

App crashes when ComboBox is declared like either

ComboBox {
width: 200
model: [ "Banana", "Apple", "Coconut" ]
}

or

ComboBox {
width: 200
model: ListModel {
ListElement

{ text: "Banana"; color: "Yellow" }

ListElement

{ text: "Apple"; color: "Green" }

ListElement

{ text: "Coconut"; color: "Brown" }

}
}

NOTE: It does not crash when ComboBox is declared like this

ComboBox {
width: 200
}
