This means that the certificate of CN="AddTrust External CA Root" is signed by itself. It's a common thing when the administrator of the respective SSL-enabled host has not bought a certificate from one of the global CA authorities, but has signed the certificate with itself to avoid the costs & process associated with maintaining a "normal" certificate. If you know that the respective domain is indeed set up this way, the warning is harmless.
