    }

Short answer.

Add after umask(0); (or before it) this Mage::app();

Long answer (may help on future problems)

I've searched for the text getModelInstance in the code and the only occurrence is in the Mage_Core_Model_Config class.

It is used in 3 locations.

2 of them are called from inside the class itself with $this->getModelInstance(). This cannot be the problem because you cannot have $this to be null if you are already inside the class.

The other place is when calling Mage::getModel() and it is called like this self::getConfig()->getModelInstance($modelClass, $arguments);.

This means that Mage::getConfig() returns null for some reason.

The method getConfig only returns self::$_config.

Checking where this config is initialized, you will see that you have to run Mage::app() or Mage::init() or Mage::run() to make it have a value.
