The feedback shell issue

Steps to reproduce the issue:

- start to drag some IDE part
- after a while the following exception should occur:

java.lang.NullPointerException
	at org.eclipse.e4.ui.internal.workbench.ModelServiceImpl.combine(ModelServiceImpl.java:564)
	at org.eclipse.e4.ui.internal.workbench.ModelServiceImpl.insert(ModelServiceImpl.java:600)
	at org.eclipse.e4.ui.workbench.addons.dndaddon.SplitDropAgent.dock(SplitDropAgent.java:377)
	at org.eclipse.e4.ui.workbench.addons.dndaddon.SplitDropAgent.drop(SplitDropAgent.java:182)
	at org.eclipse.e4.ui.workbench.addons.dndaddon.DragAgent.dragFinished(DragAgent.java:159)
	at org.eclipse.e4.ui.workbench.addons.dndaddon.PartDragAgent.dragFinished(PartDragAgent.java:111)
	at org.eclipse.e4.ui.workbench.addons.dndaddon.DnDManager.finishDrag(DnDManager.java:276)
	at org.eclipse.e4.ui.workbench.addons.dndaddon.DnDManager.startDrag(DnDManager.java:243)

The exception causes that the feedback shell stays visible (see attachment). After the exception the Workbench is still usable (i.e. we can type in the editor or modify the selection)

> start to drag some IDE part

To be more precise - drag and move between different containers some IDE part and finally drop it into the new container
