[Bug 974667] [NEW] dnsmasq does not bind to a port

[Jacek N]

Public bug reported:

When I boot into the installation CD (kubuntu-12.04-beta2-desktop-i386)
DNS service does not work properly. resolv.conf points to 127.0.0.1
which seems correct, /var/run/nm-dns-dnsmasq.conf contains correct
nameserver IP.

I think it is to do with the fact that nothing listens on port 53.
kubuntu at kubuntu:~$ sudo netstat -nlptu|grep 53
udp        0      0 0.0.0.0:5353            0.0.0.0:*                           1173/avahi-daemon: 
udp6       0      0 :::5353                 :::*                                1173/avahi-daemon:
kubuntu at kubuntu:~$

dnsmasq is running:
kubuntu at kubuntu:~$ ps -ef|grep /usr/sbin/dnsmasq
nobody    1275  1191  0 21:17 ?        00:00:00 /usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces --pid-file=/var/run/sendsigs.omit.d/network-manager.dnsmasq.pid --listen-address=127.0.0.1 --conf-file=/var/run/nm-dns-dnsmasq.conf --cache-size=0 --proxy-dnssec

When I do lsof it show interesting results:
kubuntu at kubuntu:~$ sudo lsof|grep 1275
<info ommited>
dnsmasq   1275     nobody    3r     sock        0,7      0t0      11578 can't identify protocol
dnsmasq   1275     nobody    4w     FIFO        0,8      0t0      11587 pipe
dnsmasq   1275     nobody    5u     FIFO        0,8      0t0      11587 pipe
dnsmasq   1275     nobody    6u     unix 0xec3126c0      0t0      11589 socket

If I kill the process, recreate /var/run/nm-dns-dnsmasq.conf and start it on the CLI manually everything is fine (I can resolve hostname and and dnsmasq binds to the port 53)
kubuntu at kubuntu:~$ sudo netstat -nlput|grep 53

I am using VirtualBox 4.1.12 for testing with almost default config of
my VM. It happens every time so if you need any more details I can
provide them easily.
