Bug 1759102

+++ This bug was initially created as a clone of Bug #1752123 +++

Description of problem:

On Chromium 76.0.3809.132, when I log into the oVirt engine and navigate to "Compute -> Virtual Machines", no VMs are visible and I get a JavaScript error:

> Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'isEval' of undefined
> Please have your administrator check the UI logs

The error doesn't appear in Firefox 69.0. 

Version-Release number of selected component (if applicable):

Chromium: 76.0.3809.132
oVirt: 4.3.5.5-1.el7 (hosted engine)

How reproducible:

Very on my setup (not sure if it's setup-related).

Steps to Reproduce:
1. Log into web admin as an administrator
2. Navigate to Compute -> Virtual Machines

Actual results:

Error message described above. JS console shows an obfuscated stack trace:

Expected results:

VMs are shown and there's no error messages.

This is not reproduced to me. Can you please attach engine and ui logs once it occurs? 
In addition, please try to clear the browser cache and see if it's reproduced.

Does other views except the VMs (Clusters, Templates) work for you under the Compute menu?

Same issue observed, this was already happening with 4.2, remained after update to 4.3.
Log shows successfull login/test with Firefox at 15:43, then errors with Chrome. Both generate error about "SpiceVersion.txt".

Clearing cache, or disabling through DevTools does not make a difference.

Firefox works, other Compute menu items are fine.

Storage-Disks shows another error, not sure if related:
Mon Sep 16 15:55:25 GMT+200 2019 org.ovirt.engine.ui.uicompat.EnumTranslator
WARNING: Missing Enum resource 'V5'. Cannot find constant 'StorageFormatType___V5'; expecting a method name

Since this issue was started at 4.2 then I guess it will be hard to reproduce. I suggest installing 4.3.6 on a clean environment and see if reproduced.
