Description of problem:
Happened during normal system use, not sure of a specific trigger.
SELinux is preventing systemd-logind from 'read' accesses on the directory dbus-1.

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

If you believe that systemd-logind should be allowed read access on the dbus-1 directory 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 'systemd-logind' --raw | audit2allow -M my-systemdlogind
# semodule -X 300 -i my-systemdlogind.pp
