crashes with this signature are regressing in volume during the 67 beta cycle.

Only one crash on 66, so wontfix for 66, but the 67 volume is noticable even though it went down in the last beta 9.

Hsinyi, could we get somebody assigned to this bug? There is an increase in 67 beta and I would like to make sure it doesn't come as a top crash when we reach release. Thanks.
