The X.509 certificate presented by the server when I direct my browser to https://svn.openclipart.org/public/openclipart is not valid for that domain. It only includes entries for the DNS names osuosl.org and *.osuosl.org.
The certificate should either be updated to include the missing DNS name, or a new, separate certificate should be used for the server.
Closing all openclipart bugs as openclipart is now on launchpad, as per request from Jon Philips.
