A friend of mine complained that empathy on f13 doesn't find his systems certificates. The problem seems to be that telepathy-gabble has this code: /* system certs */ wocky_connector_add_ca (priv->connector, "/etc/ssl/certs/ca-certificates.crt"); While the ca-certificates package installs a file called /etc/ssl/certs/ca-bundle.crt
