Description of problem:
SELinux is preventing gnome-thumbnail from read, write access on the chr_file /dev/tty2.

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

If you believe that gnome-thumbnail should be allowed read write access on the tty2 chr_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-thumbnail' --raw | audit2allow -M my-gnomethumbnail
# semodule -X 300 -i my-gnomethumbnail.pp
