Bug Description

Message:
$ dmesg | grep dnsmasq
[ 26.053414] dnsmasq[1687]: segfault at 7fff168a8ff8 ip 00007f06425f31a8 sp 00007fff168a8fd0 error 6 in libc-2.17.so[7f0642572000+1be000]

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

$ lsb_release -rd
Description: Ubuntu 13.04
Release: 13.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center

$ apt-cache policy dnsmasq-base
dnsmasq-base:
  Installed: 2.65-1ubuntu1
  Candidate: 2.65-1ubuntu1
  Version table:
 *** 2.65-1ubuntu1 0
        500 http://id.archive.ubuntu.com/ubuntu/ raring/main amd64 Packages
        100 /var/lib/dpkg/status

3) What you expected to happen

1. Make file /etc/NetworkManager/dnsmasq.d/hostname:
bind-interfaces
host-record=hostname,192.168.0.100
ptr-record=hostname
cname=hostname,hostname

2. Restart

3. 'ps aux | grep dnsmasq' still shows entry of network-manager dnsmasq-base instance.

4. 'ping hostname' success.

4) What happened instead

1. 'ps aux | grep dnsmasq' shows entry of libvirt-bin dnsmasq-base instance. network-manager dnsmasq-base instance dissapeared.

$ ps aux|grep dnsmasq
115 2177 0.0 0.0 26080 1020 ? S 08:58 0:00 /usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf
rona 26651 0.0 0.0 9440 944 pts/1 S+ 09:23 0:00 grep dnsmasq

2. 'ping hostname' fail.

I ran a test against the /etc/NetworkManager/dnsmasq.d. It says syntax check ok.

$ /usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces --pid-file=/var/run/NetworkManager/dnsmasq.pid --listen-address=127.0.1.1 --conf-file=/var/run/NetworkManager/dnsmasq.conf --cache-size=0 --proxy-dnssec --enable-dbus=org.freedesktop.NetworkManager.dnsmasq --conf-dir=/etc/NetworkManager/dnsmasq.d --test
