Subject: Bug#1530: TLS intermediate certificate seems to be "wrong"

Package: wiki.x2go.org

While checking URLs with LWP/curl, I noticed that
wiki.x2go.org fails:

| [tim@passepartout ~]$ curl https://wiki.x2go.org/
| curl: (60) SSL certificate problem: unable to get local issuer certificate
| More details here: https://curl.haxx.se/docs/sslcerts.html

| curl failed to verify the legitimacy of the server and therefore could not
| establish a secure connection to it. To learn more about this situation and
| how to fix it, please visit the web page mentioned above.

Staring at "openssl s_client -connect wiki.x2go.org:443",
https://www.ssllabs.com/ssltest/analyze.html?d=wiki.x2go.org
and https://letsencrypt.org/certificates/ suggests to a
layman that the server certificate is signed by the R3
certificate, but the X3 certificate is sent along?
