test_scene_selector_operation failed from mako #76

[Brendan Donegan]

This test is failing frequently on mako, last seen in image #76. This is the error that is given:

Traceback (most recent call last):

This looks like autopilot was unable to introspect the media player application, perhaps because it didn't start. I haven't been able to reproduce this locally despite many reruns, but it seems to fail frequently in CI so this bug will track it to being fixed (eventually).

Failed again on #77 with the same error.

[Brendan Donegan (brendan-donegan)]

This test is failing because of the crash in the duplicate bug. When that is fixed it should start passing. Also this test shouldn't run in the first place, because it is marked as skipped, but a bug in testtools means that its setUp is run anyway.
