PHP Error

Hi Guys,

i’m running the most recent version of the plugin. With (manual) minified settings enabled, I see the following PHP warning in my PHP error logs:

Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 0 in /home/users/topogftp/topografieindeklas.nl/wp-content/plugins/w3-total-cache/lib/W3/Plugin/Minify.php on line 1178

That specific line is the following, part of the function below:
if ($expr != '' && preg_match('~' . $expr . '~i', $_SERVER['REQUEST_URI'])) {

function check_request_uri() {
        $auto_reject_uri = array(
            'wp-login',
            'wp-register'
        );

        foreach ($auto_reject_uri as $uri) {
            if (strstr($_SERVER['REQUEST_URI'], $uri) !== false) {
                return false;
            }
        }

        $reject_uri = $this->_config->get_array('minify.reject.uri');
        $reject_uri = array_map('w3_parse_path', $reject_uri);

        foreach ($reject_uri as $expr) {
            $expr = trim($expr);
            if ($expr != '' && preg_match('~' . $expr . '~i', $_SERVER['REQUEST_URI'])) {
                return false;
            }
        }

        w3_require_once(W3TC_LIB_W3_DIR . '/Request.php');
        if (W3_Request::get_string('wp_customize'))
            return false;

        return true;
    }

I know this warning has been here for over a year. Any thoughts on a bug-fix for this prey-match, or any other solution/thoughts?
