Crash when an item lost the focus

When an item lost the focus to another ther is a segfault.

Here is a simple that make the application crash.

import QtQuick 2.0
Rectangle {
width: 100
height: 100
Column{
spacing:15
Rectangle{
id:input
color:"green"
onFocusChanged:

{ color=focus?"red":"green" }

width:20
height:20
MouseArea{
anchors.fill : parent
onClicked:

{ parent.focus = true }
}
}
Rectangle{
id:input2
color:"green"
width:20
height:20
onFocusChanged:{ console.log("here1") color=focus?"red":"green" }
MouseArea{
anchors.fill : parent
onClicked:{ parent.focus = true }

}
}
}
}

When I click on the first square it turn to red. But next when I click on the second rectangle a segfault occur.
