Description of problem:
dnf install gnome-clocks

afterwards my gnome-session was locked.
then after unlock, SELinux Troubleshooter poped up with this problem. 
SELinux is preventing gdbus from 'read' accesses on the file /home/madd/.local/share/icc/edid-64003f43a13eedaa7635f6d3e301f418.icc.

*****  Plugin restorecon (94.8 confidence) suggests   ************************

If you want to fix the label. 
/home/madd/.local/share/icc/edid-64003f43a13eedaa7635f6d3e301f418.icc default label should be icc_data_home_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /home/madd/.local/share/icc/edid-64003f43a13eedaa7635f6d3e301f418.icc

If you want to allow gdbus to have read access on the edid-64003f43a13eedaa7635f6d3e301f418.icc file
Then you need to change the label on /home/madd/.local/share/icc/edid-64003f43a13eedaa7635f6d3e301f418.icc
Do

*****  Plugin catchall (1.44 confidence) suggests   **************************

If you believe that gdbus should be allowed read access on the edid-64003f43a13eedaa7635f6d3e301f418.icc 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:
# grep gdbus /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
