Summary: SELinux is preventing /usr/sbin/rpc.gssd "getattr" access on /tmp/krb5cc_510_8YfbKD. Detailed Description: SELinux denied access requested by rpc.gssd. It is not expected that this access is required by rpc.gssd and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

This happens each time I log in. Our setup uses Kerberos 5 + LDAP for authentification and NFSv4 for home dirs (although I don't think NFS matters for the issue at hand).
Nevermind, I tweaked the booleans to allow gssd to read /tmp and this disappeared.
Looks like you have partially updated system. Probably you need to complete upgrade.
