I can't seem to import a plugin model when running controller from the cron_dispatcher. Here is a simple test result.
ver: 1.3.2 cron_dispatcher: http://tricks.cakephp.in.th/comland-line-and-cronjob
- running from web ......... [WORKS]
 - running testA function WITHOUT model import from cmd line......... [WORKS]
 - running testB function WITH model import from cmd line......... [FAILED] - No errors given
 
code:
class CronsController extends PluginAppController {
    var $uses = array();
    function testA()
    {
            echo 'Working';
            die;
    }
    function testB()
    {
            App::import('Model', 'Plugin.Report');
            $report = new Report();
            echo 'Working';
            die;
    }
