PHPMailer doesn`t work with AddAddress property set

Question

I'm trying to create a contact form using phpMailer and I get in firebug this:

NetworkError: 500 Internal Server Error - path/process.php
uncaught exception: [object Object]

each time I'm trying to run the code below.
Please note that the error is not shown anymore if I remove $mail->AddAddress line, that's why I suspect this line to be the cause.
Instead a new error is displayed: You must provide at least one recipient email address when I remove it.

<?php
$name = $_POST['firstName'];
$email = $_POST['email'];
require("phpmailer.inc.php");
$mail = new PHPMailer(true);
$mail->IsMail();
$mail->From = $email;
$mail->Subject = "subject ";
$mail->Body = "From $name with email: $email";
$mail->WordWrap = 50;
$mail->AddAddress('my_address@gmail.com','my name');
$mail->Send();
?>

Thanks!

Rewrite it to:

<?php
$name = $_POST['firstName'];
$email = $_POST['email'];
require 'phpmailer.inc.php';
try {
    $mail = new PHPMailer(true);
    $mail->IsMail();
    $mail->From = $email;
    $mail->Subject = "subject ";
    $mail->Body = "From $name with email: $email";
    $mail->WordWrap = 50;
    $mail->AddAddress('my_address@gmail.com','my name');
    $mail->Send();
} catch (Exception $e) {
    echo $e->getMessage();
}

and you will catch the error
