Title:
  outdated version of libvirt-python 1.3.1 crashes on call to
  getAllDomainStats

Status in libvirt-python package in Ubuntu:
  Fix Released
Status in libvirt-python source package in Xenial:
  Fix Released

Bug description:
  [Impact]

   * bad free from libvirt python, getAllDomainStats is unusable

   * mostly python based stat apps like Ceilometer would be affected

   * fix is an upstream backport.

  [Test Case]

   * Execute the test program I wrote in comment #2

  [Regression Potential]

   * it seems that so far any user of getAllDomainStats would have 
     segfaulted. What comes to my mind are solutions that worked before that 
     happened and ignored the latter segfault. By a change in behavior it 
     might now behave different. Still I think that is of very low risk.

  [Other Info]
   
   * n/a

  The following bug is present in the curent version of libvirt-python
  in Xenial (1.3.1):

  https://bugzilla.redhat.com/show_bug.cgi?id=1326839

  This bug has been resolved in 1.3.4 by the following commit:

  https://gitlab.com/libvirt/libvirt-
  python/commit/e9c4e2abffef007a28112ebb40a9586b0128f10b

  This bug is e.g. triggered when using OpenStack Telemetry (Ceilometer)
  and configuring it to collect "cpu" metering data. This leads to the
  segmentation fault mentioned in the linked bug report.

  The version of libvirt-python in Xenial should be updated to >= 1.3.4
  or at least the linked fix should be backported.
