This is happning because there is a problem with your mail configuration. I have 2 suggestions:

1. Open app/code/core/Mage/Adminhtml/Block/Sales/Order/View.php at line number 92 replace your code with below code:

if ($this->_isAllowedAction('emails') && !$order->isCanceled()) {
    $confirmationMessage = $coreHelper->jsQuoteEscape(
        Mage::helper('sales')->__('Are you sure you want to send order email to customer?')
    );
    $this->addButton('send_notification', array(
        'label'     => Mage::helper('sales')->__('Send Email'),
        'onclick'   => "confirmSetLocation('{$confirmationMessage}', '{$this->getEmailUrl()}')",
    ));
}

Then clear your cache, refresh the page and see if your error is gone.

2. Open app/code/core/Mage/Adminhtml/Block/Sales/Order/View.php at line number 92, uncomment this code and then clear your cache, refresh the page and check whether your error is gone.
