That's coming out of the GnuTLS library.

A quick web search finds:
"In any case, the problem is with your server's X.509 certificate chain: Either the server certificate itself or another certificate in the chain has a key usage restriction that is violated. For example a certificate with a key usage restriction to signing cannot be used to authenticate TLS connections. See section 4.2.1.3 of RFC 5280."
