Javascript error on click of button when permission not set: Uncaught TypeError: Cannot read property 'type_name' of undefined

From plugin.js:

 // Overrides linkType definition.
        var infoTab = definition.getContents('info');
        var content = getById(infoTab.elements, 'linkType');
        content.items.unshift([Drupal.settings.ckeditor_link.type_name, 'drupal']);
plugin.js:109 Uncaught TypeError: Cannot read property 'type_name' of undefined

When a user doesn't have permission to "access ckeditor link" and they try to use a CKEditor profile with the link configured, the whole page blows up. Granting the permission fixes.

Great module! thanks.
