Document icons != window icons; window icons should be the dock icon  
(if I remember the api correctly)

Well; thats not my vote because I'll forget to implement it then.   
Thats why these things throw exceptions so people whine and they come  
to my attention as needed.
Would you care to send a patch that sets the dock icon in that case;  
and if I change the behvaiour later to a document icon we can still  
sue the dock code elsewhere?
