It's a private class used in the implementation of NSView.
What this likely means is that your observer object was deallocated, and
that location in memory was reused for an object that happened to be of
class _NSViewAuxiliary.
There are a couple of different possible causes.
(1) The view was deallocated prematurely.
(2) You didn't remove the view as an observer of the notification prior to
the view's destruction.
Search for NSZombieEnabled for some possible help debugging.
