Code review comment for lp://staging/~3v1n0/autopilot/badwindow-errors-protect

This looks good to me, but I believe this is for the Unity test cases? If so this should be against https://code.launchpad.net/~autopilot/autopilot/legacy (autopilot-legacy, autopilot-desktop-legacy) which is under the stewardship of the Unity7 team.
