Sorry, case of temporary ENOTIME and I also had to prepare another
machine for the test, which took longer than expected. 

But I can confirm now that 3.18 also has the problem.

Tobias, can you please answer this question, i.e. try 3.18 from testing
and see if that shows the same behaviour.

Atm, this bug blocks gdm3 and a lot of other important GNOME 3.20 from
entering testing.

Do you think it's a regression from 3.18? TBH, I think I already saw 
this behavior in the past.


Also, do you think you could bring this upstream?
