[libvirt] Segfault in libvirt with lxc driver



Hi,

I am running libvirt 0.10 on debian [1] and I am getting the following
segfault [2] about once a day when using the lxc driver. I don't know
how to reproduce the circumstances unfortunately. It seems to happen
when destroying domains. I attached the debug log leading up to the
segfault. Is this useful? Do you need more information?

best, Tom
