Every so often, many of the pixel integration tests fail, with a message like this:

(/b/s/w/ir/third_party/catapult/telemetry/telemetry/internal/backends/chrome_inspector/inspector_backend.py:470 _ConvertExceptionFromInspectorWebsocket) The app is probably crashed:

there is no minidump and no stack trace. Here is an example build displaying this problem:

https://uberchromegw.corp.google.com/i/chromium.gpu/builders/Mac%20Release%20%28Intel%29/builds/67741

some of the failing tests include:

gpu_tests.pixel_integration_test.PixelIntegrationTest.Pixel_CSSFilterEffects
gpu_tests.pixel_integration_test.PixelIntegrationTest.Pixel_IOSurface2DCanvas
gpu_tests.pixel_integration_test.PixelIntegrationTest.Pixel_ScissorTestWithPreserveDrawingBuffer

There is no obvious pattern to the failures and successes; they all run on the same worker, so I doubt this is a sick bot.

ccameron@, can you take a look please? :)
