v5.2.4 - Use of saveEntity($user) throws Uncaught Exception TypeError

[youri]

With LDAP authentication active and working properly under version 5.1.2, if a LDAP user logged in for the first time into EspoCRM account creation worked fine.
Since upgrading from 5.1.2 to 5.2.4 EspoCRM throws an error and cannot properly use "saveEntity($user)".

[2018-06-08 07:37:00] Espo.ERROR: Uncaught Exception TypeError:
"Argument 2 passed to Espo\Core\Acl::__construct() must be an instance of Espo\Entities\User, null given,
called in /var/www/espo-5.2.4-test/application/Espo/Core/Container.php on line 255"

The user is still created, but not all settings are saved.

We run EspoCRM on Debian 9.3 with nginx/1.10.3 and PHP 7.0.27-0+deb9u1.

It will be fixed in the next release.

Thank you, we applied your fix manually and it works again.
