Country field causes form not to be submitted

[hoegrammer]

Hi, I'm making a newsletter signup form and the country is required as part of the address. But adding a country field to the profile causes the data not to be saved. Watchdog (on the CiviCRM site) shows this:

  | Notice: Undefined variable: country_id in civicrm_api3_remote_form_Countries() (line 5 of /var/www/sites/default/files/civicrm/ext/net.ourpowerbase.remoteform/api/v3/RemoteForm/Countries.php).
