===========test2.qml================
import QtQuick 2.3
import Ubuntu.Content 0.1

Rectangle { color: "pink" }

===========test.qml==============
import QtQuick 2.0

Rectangle {
    color: "red"
    Loader { id: loader; anchors.fill: parent; }
    MouseArea { 
        anchors.fill: parent
        onClicked: loader.source = "test2.qml"
    }
}

Run:

LTTNG_UST_DEBUG=1 aa-exec-click -p com.ubuntu.camera_camera_3.0.0.611 --
qmlscene test.qml --desktop_file_hint=dialer-app

which enables extra LTTng output. I get some from Mir at startup - still
no LTTng warning messages printing. But then I hit the screen, to load
Ubuntu.Content plugin. I then get messages that ubuntu-app-launch
registers tracepoints, and the warning messages start repeating.

My log here: http://pastebin.ubuntu.com/14883688/

Maybe UAL imported as library is doing it? I don't know yet

Bug description:
  Confined apps don't have access to this and continuously produce this
  error message in stderr:

  libust[31283/31285]: Error: Error opening shm /lttng-ust-wait-5 (in
  get_wait_shm() at lttng-ust-comm.c:958)

  
  This is printed to the application's log about once every other second and makes it hard to read the application's own debug output. For a better app developer experience this message should be silenced.
