Bug 34335 DND doesn't work
RC2 Linux-GTK Drag and drop doesn't work. I've tried it in the DNDExample and in the package explorer and drags are never initiated.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/typehierarchy/TypeHierarchyViewPart.java
/*
	 * @see ViewPart#saveState(IMemento)

	public void saveState(IMemento memento) {
		if (fPagebook == null) {
			
			if (fMemento != null) { 
				memento.putMemento(fMemento);
			}
			return;
		}
		if (fInputElement != null) {
			String handleIndentifier=  fInputElement.getHandleIdentifier();
			if (fInputElement instanceof IType) {
				ITypeHierarchy hierarchy= fHierarchyLifeCycle.getHierarchy();
				if (hierarchy != null && hierarchy.getSubtypes((IType) fInputElement).length > 1000) {
					
					handleIndentifier= null;
				}
			}
			memento.putString(TAG_INPUT, handleIndentifier);
		}		
		memento.putInteger(TAG_VIEW, getViewIndex());
		memento.putInteger(TAG_ORIENTATION, fCurrentOrientation);	
		int weigths[]= fTypeMethodsSplitter.getWeights();
		int ratio= (weigths[0] * 1000) / (weigths[0] + weigths[1]);
		memento.putInteger(TAG_RATIO, ratio);
		
		ScrollBar bar= getCurrentViewer().getTree().getVerticalBar();
