How reproducible:
100%

Steps to Reproduce:
1.Deploy HE with rhevm-appliance-20161116.0-1.el7ev.noarch on Conroe host.
2.Once deployed, add some data storage domain to the engine and wait until hosted-storage being imported.
3.Set host in to global maintenance and update repos on appliance to latest bits and yum update the engine.
4.Run engine-setup and finish successfully with it.
5.Remove host from global maintenance.

Actual results:
Engine's VM is up, but WEBUI stuck with "Internal Server Error" on it's web page.

Expected results:
UI should get started without any issues after engine's upgrade.

Additional info:
sosreports added from engine and host.
