If you can reproduce the problem, please check to see if it happens as a result of the server (unity8) crashing.

[Daniel van Vugt (vanvugt)]

Oh here it is from the JournalErrors.txt. It appears Gnome Screensaver failing to connect to the server (which is expected with Unity8 since it will reject regular apps) has indirectly led to Xmir crashing.

So how or why is Gnome Screensaver running?...

OK, I've generalised bug 1627311. This appears to be the same issue.
