Fascinating: this assertion is the reason I backed Kip out, and we did merge the backout, https://hg.mozilla.org/mozilla-central/rev/46da19b55672, rather than merging the landing and then realizing that oops there was a backout above there, but apparently my theory that we were still seeing these on mozilla-inbound above the backout was just because debug emulator needed a clobber wasn't correct, since https://treeherder.mozilla.org/logviewer.html#?job_id=3646493&repo=b2g-inbound

No idea how enabling it could cause permanent assertions that hadn't been seen before, and then redisabling it could cause the assertions to be intermittent. Does the b2g emulator fail to properly create a clean new profile from the build being tested, so we have stale profiles from the period while it was on m-i being used for test runs on b-i?
Oh, the light dawns at last. Bug 1182048 landed 15 seconds before bug 1218482, so we didn't get the b2g debug build which runs the tests on the former, it got coalesced onto the latter and we didn't see tests run on just the former. So enabling WebVR caused permaorange assertions, but making it possible to have both WebVR and e10s enabled caused intermittent assertions even when it isn't enabled.

This assert() is erroneous, a remnant of debugging, and can be removed.

MozReview Request: Bug 1235803 - Remove erroneous assertion

https://reviewboard.mozilla.org/r/29255/#review26053

kip was looking for someone to r+, in #gfx; I'll rubber-stamp this, on kip's assurance that this pointer can be already-null at this point without causing any issues. (and kip's in a good positition to make that assessment, as he was the one to add this code & add this assertion)
