Comment 4 for bug 1239753

> $ initctl set-env QT_LOAD_TESTABILITY=1 && start maliit-server

That looks reasonably elegant. I tried that, but I still get the error from comment 2. With the maliit-server.override approach I get a different crash:

  File "/home/phablet/messaging-app/tests/autopilot/messaging_app/tests/test_messaging.py", line 102, in test_write_new_message
    self.close_osk()
  File "/home/phablet/messaging-app/tests/autopilot/messaging_app/tests/test_messaging.py", line 154, in close_osk
    kb.dismiss()
  File "/usr/lib/python2.7/dist-packages/ubuntu_keyboard/emulators/keyboard.py", line 170, in dismiss
    self.keyboard.state.wait_for("HIDDEN")
  File "/usr/lib/python2.7/dist-packages/autopilot/introspection/dbus.py", line 234, in wait_for
    failure_msg))
AssertionError: After 10.0 seconds test on QQuickItem.state failed: 'HIDDEN' != dbus.String(u'SHOWN', variant_level=1)

It's notable that for both approaches the application crashes the first time after running the test after restarting maliit, the second time it injects an additional "00" keyboard keys into the application, and only at the third time it actually starts functioning normally. That sounds like a bug in maliit itself, though.
