because nginx pass to backend https:// url in Destination header.

but http:// and https:// urls can not be mixed in COPY request.

workaround available:

        server_name www.mydomain.com;

        location /myproj/repos {

                set $fixed_destination $http_destination;
                if ( $http_destination ~* ^https(.*)$ )
                {
                    set $fixed_destination http$1;
                }

                proxy_set_header        Host $host;
                proxy_set_header        X-Real-IP $remote_addr;
                proxy_set_header        Destination $fixed_destination;
                proxy_pass              http://subversion_hosts;
        }
