Changing the scene graph during event traversal shouldn't be a problem and shouldn't require you do set the Drawable and StateSet to DYNAMIC unless you are modifying the contents of these objects. The only area that might be worth looking at is if the draw traversal is access the parent lists of the Drawable and/or StateSet while these are being modified by the event traversal. There isn't anything further I can suggest bassed on so few details about the actual crash. Please run your application in a debugger and get a strack trace. Also considering using a thread debug tool.
