This appears to be an intermittent shutdown crash which we also saw on Linux in automation, see: https://treeherder.mozilla.org/logviewer?job_id=362239866&repo=autoland&lineNumber=3818

Haven't seen this since I fixed bug 1748647 so most likely a dup.

This showed up again

While working on bug 1750763 I finally got a reproducible STR: follow the steps in bug 1750763 comment 0 then shut down Firefox while the music is still playing. I'll work on this tomorrow.

Status: REOPENED → ASSIGNED

This patch fixes two different issues: accessing the MIDI service after
it has shut down and sending MIDI messages through ports that have
already been closed. In both cases we just drop the operation since it
has become meaningless.

Pushed by gsvelto@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/eaeaf7286193 Do not process MIDI runnables after shutdown r=padenot

Backed out for causing mochitest failures on test_midi_permission_gated.html.
