Multiple notices when creating a post via BlogAPI

When I create a post using ScribeFire 1.4.2, the following errors are shown on the next page view on the Drupal site:

• notice: Undefined property: stdClass::$last_open in C:\xampp\htdocs\drupal\drupal-6.x-dev\includes\xmlrpc.inc on line 259.
• notice: Undefined index: mt_excerpt in C:\xampp\htdocs\drupal\drupal-6.x-dev\modules\blogapi\blogapi.module on line 640.

Not sure what the significance of all this is ... whether it's a ScribeFire problem or a Drupal problem. Either way, it's pretty ugly!

Also I had a few similar errors when first "logging in" to Drupal from ScribeFire.
