Description of problem:
Happened during a straightforward 'boot and run a default install' test on Fedora-Workstation-Live-x86_64-Rawhide-20170115.n.0.iso .
SELinux is preventing gdm-session-wor from 'view' accesses on the key Unknown.

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

If you believe that gdm-session-wor should be allowed view access on the Unknown key 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 'gdm-session-wor' --raw | audit2allow -M my-gdmsessionwor
# semodule -X 300 -i my-gdmsessionwor.pp
