>From the related code path the following happens:

Object_Factory::createUMLObject() 
        calls Object_Factory::createNewUMLObject() 
        which 
               1. creates the object
               2. add it to the undo list
               3. signals object creation
(UMLApp::app()->document()->signalUMLObjectCreated(o);)
               4. call qApp->processEvents() to handle signals/slots  
               5. return

The list view is connected to the signal mentioned in 3.  It creates the list
view entry and adds it to the list view. The question is if this is completly
handled by 4. 

To be sure about that, a test case header file is required.
