We could fix this problem like this: - config->setSyncURL("http://m.google.com/syncml"); + config->setSyncURL("https://m.google.com/syncml"); config->setWebURL("http://m.google.com/sync"); config->setClientAuthType("syncml:auth-basic"); config->setWBXML(true); config->setConsumerReady(true); + // temporarily (?) disabled certificate checking because + // libsoup/gnutls do not accept the Verisign certificate + // (GNOME Bugzilla #589323) + config->setSSLVerifyServer(false); + config->setSSLVerifyHost(false); The problem with that is that the non-standard "verify off" values will be permanently written into users' config.ini. Updating SyncEvolution to a version were they are on by default will not update those values, users would have to do it manually.
