Bug 983903

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:46.0) Gecko/20100101 Firefox/46.0
Build Identifier: 

I am using openSUSE Tumbleweed which is version 20160530. After that I updated to version 20160605 with zypper dup command. 
I was reboot then gdm crashes because of too many attempts to start.
The problem is according to the journalctl messages
as follows:

# journalctl -r

this logs looping
In each time it wants to start again, but does not succeed.

These messages are repeating (with increasing session numbers) certain times and than *NO* Login Screen appears. Instead the screen is frozen. lightdm is working with gnome.


Reproducible: Always
