1442645 - [mozlog] mozlog.structuredlog: Failure calling log handler, due to KeyError: 'subtest'

Status: NEW

(Testing :: Mozbase, defect, P3)

Description

[Bryce Seager van Dyk [:bryce] (he/him) - Not reading bugmail]

When running

`./mach mochitest dom/media/tests/mochitest/test_getUserMedia_[a-m]* --use-test-media-devices`

if I encounter test failures (which you can do in this case by stealing focus from the testing window), when the tests finish instead of getting a clean log I get the following:
