Can you tell us exactly how you shutdown the computer so we can try to reproduce it?
Can you reproduce it with a clean profile?

Comment 2

¡Hola Mats!

All I do is this without closing Nightly first:

 - Click "Start" bubble
 - Click "Shut down"

Comment 3

[Mats Palmgren (inactive)]

Alex, can you reproduce this with E10S disabled?

Comment 4

[alex_mayorga]

I haven't seen this crash signature in a while on Nightly, let's hope it stays this way...

Comment 5

[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.)
