It looks like the patch from bug 151425 that was trying to paper over the crash only shifted it to this signature. The root cause is still causing problems.

[Al Billings [:abillings - ex-MoCo]]

Ryan, is this just a dupe of bug 1516425 and we need to re-open that issue? Is 1516425 incomplete? Since it is on Beta, we need to figure that out soon.

[Tracking Requested - why for this release]:
The next release is the 2019-03-19 and we probably don't want to ship that bug.

[Ryan Hunt [:rhunt] (on leave until early May)]

Yes, this is a duplicate of bug 1516425. The special paper-over patch for Beta 66 didn't resolve the issue in Beta.

[Liz Henry (:lizzard) (relman/hg->git project)]

Tracking this in bug 1516425.
