Comment (by crschmidt):

 When navigating away from the page, there is probably an error, because
 the ovmap 'unload' binding destroys the map:

         this.unloadDestroy = this.destroy.bindAsEventListener(this);
         // always call map.destroy()
         OpenLayers.Event.observe(window, 'unload', this.unloadDestroy);

 Since this is the case, destroy() may get called twice -- once by the
 overview map, once by the unload event.
