Tracking as this is a new crash during soft code freeze, if we can't get a patch today, we will have to backout bug 1420677 (P3 bug) for 67 before the final merge.

[Valentin Gosu [:valentin] (he/him)]

This is risky to try to fix during the soft freeze. I think we should backout 1420677 and try again next week.
