Description of problem:
Happens everytime you log in 

Problem started occurring after upgrading to lightdm-gtk-2.0.5-1.fc27.x86_64.

With previous version of lightdm-gtk there were no problems.

SELinux is preventing at-spi-bus-laun from 'map' accesses on the file /var/log/lightdm/.config/dconf/user.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that at-spi-bus-laun should be allowed map access on the user file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'at-spi-bus-laun' --raw | audit2allow -M my-atspibuslaun
# semodule -X 300 -i my-atspibuslaun.pp
