Code review comment for lp:~chris.gagnon/autopilot/add_press_duration_to_touch_devices

It looks like my test are failing for the same reason the other tests are failing.

  File "/usr/lib/python2.7/dist-packages/autopilot/introspection/__init__.py", line 173, in get_proxy_object_for_existing_process
    raise ProcessSearchError(message_string)
ProcessSearchError: Search criteria (pid = 3675, dbus bus = 'session', object path = '/com/canonical/Autopilot/Introspection', process object = '<subprocess.Popen object at 0xb448d150>') returned no results
