Testing new aethercast changes (https://requests.ci-train.ubuntu.com/#/ticket/1620) and found unity8 is crashing when it switches after a timeout automatically to the lock screen.

Incomplete:
We probably need to convince the automatic retracer to provide better stack traces. You might be able to get that by running: ubuntu-bug <crashfile>

[Simon Fels (morphis)]

@Danial: You can easily do that with the attached crash file. So what also would a ubuntu-bug provide?
