Wait, I'm confused. That code in EventManager::damage isn't calling into 
  a Graphic, it's calling into PositionalFocus or NonPositionalFocus. 
Neither PositionalFocus nor NonPositionalFocus ::damage deal with 
Graphics themselves. Where's the exception being thrown from? If you 
turn on trace, does it show PositionalFocus::damage being entered?

(I'll try to reproduce it myself if I can, but it sounds like a tricky 
sort of timing issue is necessary to do so.)
