DateTimeColumn PHP7.2

[ATr-URMA]

Hello
I've updated my PHP Version from 7.1 to 7.2 and receive now an Error in the count() Function:

Warning: count(): Parameter must be an array or an object that implements Countable
in vendor\sg\datatablesbundle\Datatable\Column\DateTimeColumn.php (line 88)

The result is, that the table doesn't show up and i get an error message on the screen.

I can reproduce the issue on two different systems:
System1(dev):
OS: Windows Server 2012 R2
Webserver: PHP CLI
PHP version: 7.2.7
Symfony: 3.4.14
Datatables Bundle: 1.0.4

System2(prod):
OS: freeBSD 10.1
Webserver: Apache 2.4
PHP version: 7.2.7
Symfony: 3.2.13
Datatables Bundle: 1.0.1

When i switch back to PHP 7.1.19, the error disapperas and application is working.
Is it possible to make it work with PHP 7.2?

Best Regards
