Hi all,
after a bunch of sleepless nights I found the solution ;-) I have to 
overwrite the init() method in my DiagramActionBarContributor:

/**
* @generated NOT
*/
public void init(IActionBars bars, IWorkbenchPage page) {
	super.init(bars, page);
	// print preview
	IMenuManager fileMenu = 
bars.getMenuManager().findMenuUsingPath(IWorkbenchActionConstants.M_FILE);
	assert fileMenu != null;
	IAction printPreviewAction = new RenderedPrintPreviewAction(new 
EnhancedPrintActionHelper());
	fileMenu.insertBefore("close", printPreviewAction); //$NON-NLS-1$
	IAction pageSetupAction = new 
org.eclipse.gmf.runtime.diagram.ui.actions.internal.PageSetupAction();
}

That's all.

Greetz,
R.
