milo, this one is probably caused by a parallel access to view hierarchy from different threads. Could you please provide a way that we can access the hierarchy and rely upon the fact that the hierarchy does not change meanwhile? Other similar issues are bug #193362 or bug #194476.
Comment 4 Miloslav Metelka 2011-01-21 16:11:58 UTC 
I've made some more tracing by DocumentView.LOG and added o.n.editor.Utilities.runViewHierarchyTransaction().
