Hm, probably not the same thing then. Usually a "crash" is when A little
red exclamation point comes up and says "Python exited!" Presumably this
wass still happening after you commented out appuifw.app.set_exit()...

I've run into strange situations before where it seems like I'm in a
loop, but I call a Listbox or other appuifw construct, and I just kind
of drop out the bottom of the program. If you make an e32.lock and
wait() on it at the beginning of the program (and only unlock via the
exit_key_handler), then you should be able to ensure this doesn't
happen... although I don't yet have the free time to go through and try
this myself.
