False positive

[samy]

Hi
A false positive is detected on Prestashop modules because of this line:

$this->module_key = "3a29c97ec9a1b25c459c2ed8727e6c2d";

(MD5_VAR rule)

The whole method block is:

function __construct()
{
        $this->name = 'random_name';
        $this->tab = 'front_office_features';
        $this->version = 1.4;
        $this->author = 'author';
        $this->module_key = "3a29c97ec9a1b25c459c2ed8727e6c2d";
        parent::__construct();
        $this->displayName = $this->l('Random name');
        $this->description = $this->l('Random desc');

}
