This bug is for crash report bp-2340cf24-e67a-4fca-86b0-6bb2f0190304.

Seen while looking at the nightly email spike report - this crash is present on other branches but is almost as high on nightly as on release: https://bit.ly/2tMqJp4. If you go back in Socorro 6 months, you can see this was an issue in nightly as far back as when nightly was in 64.

All of the crashes are Windows 10.

High correlation to flash:

(85.71% in signature vs 00.64% overall) Module "NPSWF64_32_0_0_142.dll" = true [85.71% vs 09.72% if startup_crash = 0]
