[avahi] Re: ** ERROR **: file dbus-protocol.c: line 814 (service_resolver_callback): assertion failed: (host_name)

[Sebastien Estienne]

it seems that it's the folowing service as it can resolve quux.local

  <service>
    <type>_telnet._tcp</type>
    <domain-name>local</domain-name>
    <host-name>quux.local</host-name>
    <port>23</port>
    <txt-record>foo=bar</txt-record>
    <txt-record>waldo=buzz</txt-record>
    <txt-record>another=record</txt-record>
  </service>
