Title:
  qemu segfault when starting virt-manager

Status in QEMU:
  Fix Committed

Bug description:
  libvirtd 1.2.3
  virt-manager 1.0.1
  qemu 1.7.92 (2.0.0-rc2)

  1. Initially virt-manager is NOT running

  2. I start a VM manually using "virsh start ...", causing a qemu
  instance to be run as

  3. I start virt-manager (just starting it, nothing special).

  4. The qemu instance segfaults with the attached backtrace.
