This can be seen when using the main domain-wide search box on at least:

 * http://webapps.ubuntu.com/partners/ <- and other webapps sites
 * http://training.canonical.com/
 * https://forms.canonical.com/sales/ <- and all other forms using the Ubuntu or Canonical theme

IIRC, it's caused by the search appliance module in Drupal using the default CSRF protection (requires form token) which ignores the external form field and defaults to 'ubuntu'.
