Hi Simon,

why is this filed in this component? What external software is suspected to be responsible here?

Comment 2

[Simon Giesecke [:sg] [he/him]]

Sorry if I got the component wrong. I guess I based it on the third_party code paths, but since that's used from servo, I guess it makes sense to move it.

S1 or S2 bugs needs an assignee - could you find someone for this bug?

Comment 4

[Sean Voisen (:svoisen)]

It's a pretty low-volume shutdown crash. I'm calling it S3.

Closing because no crashes reported for 12 weeks.
