Turyn, Michael commented on XAP-392:
------------------------------------

This is some code run as a result of a connect with someone's onClick event.  I'm having trouble tracing it back far under IE7; I'm looking at it under Firefox/Venkman:  there appears to be an exception there too, as well as when the window is initially closed, and a few at startup.  When the window is closed, the error message seems to stem from trying to destroy the node for an object (a Dojo widget?) that has already removed it from itself.

Preliminary work indicates that the bug filed here may be from PopupManager.onClick, where it's trying to locate if a click is over the currently active menu 'm':
                      ||||||||||||||||||||||||||||||||||||||||||||||                
if(dojo.html.overElement(m.domNode,e)||dojo.html.isDescendantOf(e.target,m.domNode)){[....]

Guess: Dojo still thinks the active menu is one from the window that's been closed.
 

This is a place where a non-xapMin, uncompressed, build is a good idea for debugging.
