Looks like a background crash, new in the last day or so, I only noticed because it triggered the infobar notification about unsent crashes.

I was in the midst of filing this when jcristau hit the crash: https://bit.ly/2T9DWDF. Crashes seem to go as far back as Build 20181222095037 on nightly, but there are crashes in this signature in earlier versions (but not in the same volume - 66 nightly has 116 crashes across the span of 66 nightly cycle, and a spike that started in yesterday's build 20190122215349).

Here is a possible regression range based on the spike: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=254bd88c107271f3d1c2ca9969acc0ed507f0a8d&tochange=69a2799081521866febfe2bbcbfc27b3d60133bd
