Multiple errors appear in error log while dragging an element from the Model explorer and dropping it in papyrus Diagram. The drag-and-drop itself, however, is executed properly.

The problem looks to be similar to the problem described here - 
http://dev.eclipse.org/newslists/news.eclipse.platform.swt/msg41423.html

The problem is on OS side. It only corrupts early feedback, but it doesn't influence the result of drag-and-drop.
