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.)

I'm marking this bug as INCOMPLETE, per no STR from OP. Reproducible bugs are tracked in blocked bug #1219672.
