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,
