How come the contents of Text elements aren't being properly justified?

Question

Consider the following page in a QML application:

Page {
    Text {
        anchors.fill: parent
        anchors.margins: units.gu(2)
        horizontalAlignment: Text.AlignJustify
        text: "aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaa aaa aaa aaa aaa aaa aaa aaa."
        wrapMode: Text.WordWrap
    }
}

I expect that the contents of the Text element would be justified but this is clearly not the case:

As you can see, the first line is not justified as it should be. What am I doing wrong?

Answer 1

I ran your qml snippet in this qml file on Ubuntu 13.10:

import QtQuick 2.0
import Ubuntu.Components 0.1


MainView {
    id: main
    width: units.gu(30)
    height: units.gu(35)

    Page {
        Text {
            anchors.fill: parent
            anchors.margins: units.gu(2)
            horizontalAlignment: Text.AlignJustify
            text: "aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaa aaa aaa aaa aaa aaa aaa aaa."
            wrapMode: Text.WordWrap
        }
    }
}

And I can say that it works perfectly, the text is properly justified:
