Intermittent Dojo error on zooming

I am working on a Javascript mapping app, using v.2.4 of the ArcGIS toolkit.  Recently I have been getting intermittent but frequent Dojo hanging errors when zooming (roughly once per 15-20 zooms).  The Dojo error occurs after the onZoomStart event and before the onZoomEnd; there is no intervening code of mine between these that I'm aware of (onExtentChange is fired after onZoomEnd, and I removed my onExtentChange handler with no effect).

I have so far been unsuccessful in determining what I might have done to cause this (and the entire app is way too big to try to reproduce here).  There error I see in Firebug is usually something like "_831 is undefined", and the line of code with the error is the unhelpful mega-line which defines the entire Dojo toolkit.:


Has anybody seen such hanging behavior due to zooming and know where the cause might lie? Or how to debug something like this?  Thanks in advance if so.
