World.queryAABB() failing with Dart SDK 11396 due to logged Dart bug (QueryWrapper losing treeCallback())

[Rupert Key]

Since this affects DartBox2D, thought I'd mention I've just logged http://code.google.com/p/dart/issues/detail?id=4823 

It seems dart2js is producing erroneous code that breaks QueryWrapper.treeCallback() which is used if you do a manual intersection test (World.queryAABB()).

HTH, Rupert.
