Form API checks for the $_POST variable and throws an error if not set any. The openid provider unsets the $_POST variable when presenting the user a little form to decide if she wants to login to the relying party site.

The following error is thrown:

Notice: Undefined variable: _POST in drupal_build_form() (line 309 of /path/to/my/drupal/includes/form.inc).

As mentioned in #1 solved by using $_POST = array(); instead of unset($_POST);

This can be solved easily by using $_POST = array(); instead of unset($_POST);
Here is the patch.
