OpenSUSE Install :: Guest User Able To Read Home Directory

I've created a guest user in the group "user." I'd like to limit its read access to its own home directory. However, by navigating through File system>home it's able to read my home directory. I was under the impression that users were limited to their own home directories. Am I missing something, or is there a group I can assign this guest to, to limit its read access to its own home directory? I've read about Pessulus (I use Gnome), but that seems to be geared toward limiting access to applications, not directories.

Ideally, I'd like to create a group that cannot navigate through any files except its own home directory. But it seems that if I try to do that, the guest user will not be able to execute any applications. I've read all the posts (and other forums) I could find about creating such a limited account, but the chroot jail is beyond my understanding. I get the feeling that it's geared toward networks.
