This is perhaps caused by the fix for bug 856333. After the fix for that bug reached my with the updates, I saw in the "route" output that the simple package installation did not set the metrics, so I did "sudo restart network-manager" and this made the metrics getting set. After that, while the system was sitting idle during the night, I got this crash.

Status changed to 'Confirmed' because the bug affects multiple users.

[Mathieu Trudel-Lapierre (cyphermox)]

This just looks racy, and a side-effect of the restart, nothing related to the bug that was fixed. I don't think you'd see this again, but just to be certain, it would be helpful if you could include additional information if there is a reliable way to reproduce this bug.

Thanks!

It happened to me two other times (see duplicates), but it never happened to anyone else.
