_addButton accepts 5 parameters, you pass 6. Try

$this->_addButton('button_id', array(
        'label'     => Mage::helper('adminhtml')->__('Some action'),
        'onclick'   => 'jsfunction(this.id)',
        'class'     => 'go'
    ), 0, 100, 'header');

Also your block file name should start with capital letter, app/code/local/Module/Parcel/Block/Adminhtml/Sales/Order/View.php instead of app/code/local/Module/Parcel/Block/Adminhtml/Sales/Order/view.php
