[ovirt-users] Hosted engine notifications don't work after upgrading ovirt from 3.5 to 3.6

[Stefano Danzi]

Hello,
I've made no changes than upgrading oVirt from 3.5 to 3.6
Distro is a standard CenOS 7.1

Pyton is: python-2.7.5-18.el7_1.1.x86_64

state_transition.txt hasn't an empty line as first line.
