I have NVIDIA installed and I have the repo installed as well, but I have not made any changes to it. So why all of a sudden am I getting the following popup? Is it safe? Should I accept it?

Do you want to accept this repository signature?
package_id: dummy,0.0.1,i386,data
repository_name: NVIDIA_Repository_1
key_url: ftp://download.nvidia.com/opensuse/11.3/
key_userid:NVIDIA Corporation <linux-bugs@nvidia.com>
key_id: F5113243C66B6EAE
key_fingerprint: (I'm hiding this just in case it's a security risk)
key_timestamp: Thu Jun 15 12:13:18 2006
type: gpg
Also, why am I getting it now if it's from 2006?
