[Users] migrations failing with latest master + vdsm

[Dead Horse]

I have been running EL 6.4 hosts in 3.3 mode for quite some time, I only
noticed this breakage in the latest master VDSM 4.13.x. Tagged vdsm
versions: ovirt-3.3.0<http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=shortlog;h=refs/heads/ovirt-3.3.0>and
ovirt-3.3<http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=shortlog;h=refs/heads/ovirt-3.3>do
work (if not using master which one of these should be used with 3.3
btw?)
The running version of libvirt on the hosts is:
libvirt-0.10.2-18.0.1.el6_4.14.x86_64
