Upon upgrade to 3.8.5 I get the following error:

Fatal error: Undefined class name 'eztstranslator' in /data/www/katherine/kernel/common/ezi18noperator.php on line 143
Fatal error: eZ publish did not finish its request

If I change my [RegionalSettings] to Locale=eng-GB (or comment it out) instead of the correct setting for my site of Locale=eng-AU then the site works.

*please note: I was unable to select 3.8.5 in "Affected Versions" even though it is released. So I was forced to select 3.8.4 even though this is not true)
