Since Sirius rc1 is available, I have a problem related to Sirius bundles loading in the case or an ecore model reference Sirius ecore models (viewpoint.ecore and diagram.ecore). 

Here's a simplified example that causes this problem. 

I have two ecore models: MainModel.ecore which is extensible and DiagramUse.ecore which is an extension to MainModel.ecore (see classes.jpg). Models and projects are available in diagram.zip. 

DiagramUse.ecore contains ModelRootElement EClass that has an: 
1 - EReference whose EType is "org.eclipse.sirius.diagram/model/diagram.ecore#//Description/DiagramDescription" 
2 - EAttribute whose EType is "org.eclipse.sirius/model/viewpoint.ecore#//LabelAlignment" 

Here's a scenario to reproduce the problem:
1. Import all the projects from diagram.zip into the workspace. Everything should build without error.
2. Launch a runtime (using the default parameters).
3. In the runtime's workspace, create a basic project, 
4. Inside the project, create a "MainModel Model" (available in New > Other > Example EMF Model Creation Wizards). Choose "Model Root" as the root element type.
5. Open "My.mainmodel". It contains a single "Model Root" element.
6. In "Model Root" element, create a child of type "Model Rool Element"
7. Close the editor, and close the (runtime) Eclipse.
8. Restart the runtime. Open the project, and open the "My.mainmodel"
