Comment(by 05092009):

 Just set a breakpoint in QgisApp's destructor, and close application.
 Debugger won't go there.
 Try to have a look on the code. QgisApp, as you know, is a singleton. It's
 instance is created in funcion main (main.cpp), but instance should be
 deleted in a straightforward way, by calling delete. Instead of these, no
 delete called and main just returns QApplication's exec.
 That causes all the data, associated with QgisApp to stay in memory 4ever.
