This is a very generic signature.

Comment 3

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

Updating crash signature to reflect changes to signature generation made in bug 1269817 (although reports older than a week will not be reprocessed), and adding dependency to ShutDownKill metabug.

(These probably shouldn't all be separate bugs, but I'm not going to fix that up in a mass-change.)
