Description of problem:
SELinux is preventing ibus-daemon from 'read' accesses on the lnk_file /var/lib/dbus/machine-id.

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

If you believe that ibus-daemon should be allowed read access on the machine-id lnk_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 'ibus-daemon' --raw | audit2allow -M my-ibusdaemon
# semodule -X 300 -i my-ibusdaemon.pp
