Hi Ed,

I'm back from vacation and will fix it shortly. The code actually assume the Modeling Project the model has been loaded already but there are valid cases where it is not yet true.
Comment 2 Cedric Brun CLA 2014-08-18 05:23:11 EDT 
To reproduce it on Linux (which tends to load the models slightly sooner because of the Project Explorer having a slightly different behavior)

1- Create a Modeling project. 
2- Move to the "Resource" Perspective and open the "Navigator" view. 
3- Restart Eclipse.
4- Get back to the "Navigator" view making sure you don't open or activate any Sirius specific UI
5- create a .ecore file in the modeling project you created in step 1
6- right click on it and pick initalize Ecore Diagram".
