Code review comment for lp:~zsombi/ubuntu-ui-toolkit/combobutton

I added an icon to the combobutton example:

            ComboButton {
                text: "Press me"
                objectName: "combobutton_collapsed"
                comboList: Rectangle {
                    height: units.gu(20)
                    width: parent.width
                    color: "blue"
                }
                iconSource: "call.png"

the icon gets aligned wrong, see http://ubuntuone.com/3LHlrfUwFssHkbx00v33Br
