"When I access the /gallery_remote2.php page in the browser it opens without asking for any password.

I didn't mention it before, but the gallery is based on the Drupal module image_pub which is supposed to be compatible with Gallery Remote. But even if it isn't, I don't think there's any reason f-spot should crash."
