Crash Data

This bug was filed from the Socorro interface and is 
report bp-d5246b0c-a246-4853-b4ce-497330170831.
=============================================================

Seen while looking at 55 crash stats: http://bit.ly/2eHfmrw. Currently in 55.0.3 it isn't very high ranking (#45), but it didn't have a bug associated with it.

Also affects 56 and 57.
Marco, I saw profile-before-change | Places Connection shutdown in the signature. I guess this is for you!
Flags: needinfo?(mak77)
I've already seen it (I keep an eye on crash stats usually), but it's not actionable as-is.
It means Places started closing the connection, but something didn't allow that, after 1 minute async shutdown just forcibly crashed Firefox.
Unfortunately all the information in the metadata is "state":{"progress":{}}. Not really useful. There may be a bug in how we pass it, or in async shutdown itself, but I didn't find it so far and didn't have time to dig deeper.

One thing we should do, imo, is to add a circular buffer to async shutdown keeping the last N log messages, and push those along the async shutdown metadata. Async shutdown logging may help us identify what happened just before the crash.

Marco, why did you mark it as p5?

This is impacting a lot of users on release (~100k install at least).
Hm, it should have been a P3 :(
The problem here is that there's no clear cause nor solution to this problem for now, it's really cryptic.

Maybe Fission related. (DOMFissionEnabled=1)
