Overview: ServiceBrowser fails resolving services (and hangs up), which
simultaneously stops working on both ipv4 and ipv6 interfaces (switching off
daap server).

Steps to reproduce:

1. launch in separate terminals Mono.Zeroconf test clients, monitoring ipv4,
ipv6 and both interfaces and resolving DAAP services. (`mzclient  -a ipv4 -r -t
_daap._tcp`, `mzclient -a ipv6 -r -t _daap._tcp`, `mzclient  -a any -r -t
_daap._tcp`).

2. Launch, halt and then again launch DAAP server (for example mt-daapd, or
sharing mode in rhythmbox).

Actual Results:
mzclient monitoring both interfaces hangs. Dump:
mixrin at groundshaker ~ $ mzclient -r -t _daap._tcp -a any

*** Found name = 'DAAP_share', type = '_daap._tcp', domain = 'local'
*** Found name = 'DAAP_share', type = '_daap._tcp', domain = 'local'
*** Resolved name = 'DAAP_share._daap._tcp.local', host ip = '195.19.37.153',
hostname = groundshaker.local, port = '3689', interface = '5', address type =
'IPv4', TXT Record = [Password = 'false']
*** Resolved name = 'DAAP_share._daap._tcp.local', host ip =
'2002:c313:25a0:a:222:43ff:fe00:b472%4', hostname = groundshaker.local, port =
'3689', interface = '5', address type = 'IPv6', TXT Record = [Password =
'false']
*** Lost  name = 'DAAP_share', type = '_daap._tcp', domain = 'local'

Expected Results:
mzclient monitoring both interfaces continues work. Expected Dump:
mixrin at groundshaker ~ $ mzclient -r -t _daap._tcp -a any
Hit ^C when you're bored waiting for responses.
