Comment:

 An issue with the above workaround: If there is an interface up without an
 IP address - e.g. a wired interface with the cable unplugged - you get the
 following failure in presenceservice, from
 https://bugs.launchpad.net/ubuntu/+source/sugar/+bug/297329:

 {{{

     addr = fcntl.ioctl(fd, SIOCGIFADDR, struct.pack('256s',

 IOError: [Errno 99] Cannot assign requested address
 }}}

 This then causes Sugar to fail to start, with:
