Black square in header

[Jean-Baptiste Lallement]

current build number: 122
device name: krillin
channel: ubuntu-touch/rc-proposed/bq-aquaris.en

Same on latest arale

There is a black square in the header in several applications (address-book, messaging, dialler, cf screenshots)

To display the black square:
- dialler: open 'Recent calls'
- messaging: tap on a message and go back
- contact: tap on a contact

I reproduced the bug as described above on device, but I can also reproduce it on my laptop with gallery-app (click on a photo, and then go back).

I reproduced the bug (with gallery-app on desktop) with UITK staging r1612, and verified that the bug is not present in r1611, so it broke with this MR: https://code.launchpad.net/~zsombi/ubuntu-ui-toolkit/cppActionItem/+merge/268348

[Tim Peeters (tpeeters)]

Bug can be reproduced by running the qml code below, clicking the 'next' button, and then clicking the back button in the header:

import QtQuick 2.4
import Ubuntu.Components 1.2

MainView {
    width: units.gu(40)
    height: units.gu(60)
    Component.onCompleted: pageStack.push(page1)

    PageStack {
        id: pageStack
    }

    Page {
        id: page1
        title: "one"
        Button {
            anchors.centerIn: parent
            text: "next"
            onClicked: pageStack.push(page2)
        }
    }
    Page {
        id: page2
        title: "two"
        visible: false

        head.backAction: Action {
            iconName: "back"
            onTriggered: pageStack.pop()
        }
    }
}

I produced in the gallery app , create a new album and add several photos in it , then the menu key turns to black square and i can't change to photos or events mode , the menu key has no use at all
