=============================================================

Seen while looking at nightly crash stats, although this crash appears on other branches as well: https://bit.ly/2JVDJzR. All versions of Windows are affected, although it appears from the data Win 7 has more crashes. 

Nightly correlations for this signature show some kind of correlation to the ja locale, as well as a few other addons. Beta correlations do not show the same correlation.

Looks like a signature change.
