[:gerard-majax]

ok, so when investigated i did a mistake which confirms bug 1896054 is unrelated: https://hg.mozilla.org/try/pushloghtml?changeset=f3902038153071b60d8f8a1ec902ea83b2456097 this repro and is with the XDG changes ... https://treeherder.mozilla.org/jobs?repo=try&author=alissy%40mozilla.com&selectedTaskRun=ag6UjgZ0S76UxcGiLMVT2w.0

And from https://treeherder.mozilla.org/jobs?repo=try&revision=c3cd766bb21b56a86f95c5c900bb49002f357960 i can't prove a higher level of intermittence due to bug 1896054

[Florian Quèze [:florian]]

Looking at the history of failures in bug 1819845, it seems this failure has been stared 6 times, only on test-verify jobs, so there's likely a race condition that fails only in chaos mode.
