From following report:

Image #100, tested with mako, maliit-server crashes when starting because qtubuntu cannot create the application instance.

We do have a sleep 2 in the upstart job already, it might not necessarily be enough:

cat /usr/share/upstart/sessions/maliit-server.conf
description "Maliit OSK Server"
author "Ricardo Mendoza <email address hidden>"

# nowadays, maliit-server needs to start *after* unity8, or it crashes while
# trying to poke geometry
start on started unity8
stop on stopping unity8

# needed to fix lp:1233550
env QML_BAD_GUI_RENDER_LOOP=1

respawn

pre-start script
    sleep 2
end script

exec maliit-server

Adding bugjob to qtubuntu as well to see if there's a better way to fail without crashing in abort (so we don't generate a crash report).
