invisible application in system tray, how to identify?

[helwitch]

So, there's clearly an application in my system tray (blank space between wireless&battery in below pic), but it's got no icon, and nothing happens when I right click it. How do I find out what application it is and make it show an icon or not sit in the system tray? logging out and back in, manually restarting the xserver, even rebooting all don't fix this.

On a hunch, I'd suggest that it's possibly the adept updater.

I sigtermed adept_notify, blank space is still in the systray. Good idea tho, thanks just the same.
So, I've figured out it's an instance of python, cos it goes away when I sigterm python in ksysguard. This instance of python is eating my CPU when it's running too. How do I find out what's loading this python and make it stop?
