Description of problem:
SELinux is preventing gnome-shell from 'read' accesses on the file 5a0dbdf8cf4543589145d137c5e6de5d-unix-1024.

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

If you believe that gnome-shell should be allowed read access on the 5a0dbdf8cf4543589145d137c5e6de5d-unix-1024 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 'gnome-shell' --raw | audit2allow -M my-gnomeshell
# semodule -X 300 -i my-gnomeshell.pp
