IPv6 is defined by the RFCs to, by default, listen on IPv4 as well. The IPV6_V6ONLY \
option was added as an afterthought. It's not supposed to be the default.

The bug is in your system-wide configuration.

kdm can, however, add a workaround. It can do as the rest of KDE does: unset \
IPV6_V6ONLY by default.

Ossi:
#if defined(IPPROTO_IPV6) && defined(IPV6_V6ONLY)
      int on = 0;
      if (setsockopt(m_sockfd, IPPROTO_IPV6, IPV6_V6ONLY, (char*)&on,
                     sizeof(on)) == -1)
        {
          return false;         // error
        }
      return true;              // success
#endif

Add this after the socket is created.
