This is because the property mapper needs the reflection service to determine the property type. So an instance of the reflection service has to be injected to the property mapper before it can be used.

The property mapper isn't a singleton, but the reflection service is:

$propertyMapper = t3lib_div::makeInstance('Tx_Extbase_Property_Mapper');
$propertyMapper->injectReflectionService(t3lib_div::makeInstance('Tx_Extbase_Reflection_Service'));

should work. Keep in mind that this is no API and may change in future.
