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.
