tor DNS resolver unable to handle/return SRV type DNS records

Tor's internal DNS resolver is incapable of looking up SRV (service type) DNS records.

SRV-type DNS records have the following format: _service._protocol.name (like "_sip._udp.ekiga.net" for example). The "output" I am getting from tor is as follows (127.0.0.1 refers to tor's internal DNS server):

dig @127.0.0.1 _sip._udp.ekiga.net SRV

; <<>> DiG 9.7.3-P1-RedHat-9.7.3-2.P1.fc18 <<>> @127.0.0.1 _sip._udp.ekiga.net SRV ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOTIMP, id: 29790 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION: ;_sip._udp.ekiga.net. IN SRV

;; Query time: 2 msec ;; SERVER: 127.0.0.1 # 53(127.0.0.1) ;; WHEN: Wed Dec 26 00:45:05 2012 ;; MSG SIZE rcvd: 37

Note the "status" above as NOTIMP (Not Implemented). The correct output, using a "proper" DNS server (marked as xxx.xxx.xxx.xxx below) is as follows:

dig @xxx.xxx.xxx.xxx _sip._udp.ekiga.net SRV

; <<>> DiG 9.7.3-P1-RedHat-9.7.3-2.P1.fc18 <<>> @xxx.xxx.xxx.xxx _sip._udp.ekiga.net SRV ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 65507 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1

;; QUESTION SECTION: ;_sip._udp.ekiga.net. IN SRV

;; ANSWER SECTION: _sip._udp.ekiga.net. 86400 IN SRV 0 0 5060 ekiga.net.

;; ADDITIONAL SECTION: ekiga.net. 85881 IN A 86.64.162.35

;; Query time: 24 msec ;; SERVER: xxx.xxx.xxx.xxx # 53(xxx.xxx.xxx.xxx) ;; WHEN: Wed Dec 26 00:48:01 2012 ;; MSG SIZE rcvd: 82

As evident, the "status" returned is NOERROR (No Error).
