Invalid argument supplied for foreach()

I got error message: Warning: Invalid argument supplied for foreach() in xxx\wp-content\plugins\wp-survey-and-poll\wordpress-survey-and-poll.php on line 229

I fixed it by if statement:

                if (is_array($cookie_wpsap)) {
				foreach( $cookie_wpsap as $cwp ) {
					if( preg_match( '/[^A-Za-z0-9]/', $cwp ) ) {
						$illegal_char = true;
					}
				}

Can you add this fix to official repository?

Thanks!
