[Pkg-libvirt-maintainers] Bug#669457: libvirt-bin: libvirt_lxc segfault

[Samuel Hassine]

Package: libvirt-bin
Version: 0.9.11-2
Severity: important

Hi mainteners,

We are trying to run a LXC container through libvirt binary with the following command: 

/usr/lib/libvirt/libvirt_lxc --name instance-0000000c --console 22 --handshake 25 --background --veth veth1

We have the error:
