Here is another example of this crash https://treeherder.mozilla.org/jobs?repo=try&revision=9aec9ab1ab472e453c1696fe12cdfd0c84251daa&selectedTaskRun=Jr94KXqkRqO2DODgabMWFA.0. reviewbot is making a lot of noise for patches touching layout/generic/.

:andi, do you know anyone who can help take look into this issue?
