Why not let the application close normally, and then restart it using
a simple watchdog application ?

This will work just as well, avoid any potential double QApplication
initialisation problems, with the additional useful property that your
application will restart even in case of complete failure, when you do
not terminate properly.

Of course, you would have to disable the watchdog in case you were to
actually exit the app...
