Comment 0 for bug 1198277

I'm having trouble lately running test cases with autopilot. One of the problems is that I'm not able to launch the gallery application using something like:
launch_test_application('gallery-app', temp_sample_dir, app_type='qt')

In particular the backtrace that I obtain in this case is:

    Traceback (most recent call last):
      File "/usr/lib/python2.7/dist-packages/ubuntu_test_cases/memory_usage_measurement/tests/test_memory_usage.py", line 56, in test_scenario
        gallery.launch()
      File "/usr/lib/python2.7/dist-packages/ubuntu_test_cases/memory_usage_measurement/apps/gallery.py", line 37, in launch
        app_type='qt')
      File "/usr/lib/python2.7/dist-packages/autopilot/testcase.py", line 256, in launch_test_application
        return get_autopilot_proxy_object_for_process(process, emulator_base)
      File "/usr/lib/python2.7/dist-packages/autopilot/introspection/__init__.py", line 160, in get_autopilot_proxy_object_for_process
        return get_proxy_object_for_existing_process(pid, emulator_base=emulator_base)
      File "/usr/lib/python2.7/dist-packages/autopilot/introspection/__init__.py", line 205, in get_proxy_object_for_existing_process
        raise RuntimeError("Search criteria returned no results")
    RuntimeError: Search criteria returned no results

Something that might be related is that recently a needed to update the test cases in the device (mako) to make them work and that broke them when running them in my laptop. What I needed to do was replace `proxy.pid` with `proxy.process`. At first it looked to me like `pid` was renamed to `process`, but now I think something might be wrong with this because in the code `process` seems to be clearly set to whatever is returned by `subprocess.Popen` and `pid` is set to access `process.pid`.
