Two problems with QSystemTrayIcon

I know it's been a while since you posted (and even long since I've read
the list archives), so maybe you have figured this out already, but just
in case (and so future folks can Google it)...

In order to make the tray icon disappear properly, you need to call
hide() or setVisible(False) on it first, but of course you have to do
that within your main loop. So you'll probably need to hook your quit
signal up to a helper function that will hide the tray, then actually exit.

Hope this helps,
