I've tried overriding destroy functions in the abiwidget control and 
connecting to the "destroy" and "delete_event" events. Nothing ever seems 
to get called. Reading through the EOG code implies that merely overiding 
the destroy functions should work. But it didn't for me.

I'll look into the nautilus-adapter code to see if there is some clue as 
to what signal it gives the control when it disconnects.

Thanks for your help Jason.
