Unknown Item in Tray
 

I installed Red Hat 9 and modified my panel. I added a system tray so that i can use the KDE Keyboard Tool and KGet. When i finished i realized that there was also a grey square there that i can't get rid off. I saw my share of linux screenshots in the internet and thats the first time i see something like this. Is there a way to turn this thing off.

Here is a screenshot to see what i'm talking about.

If you know how to remove this plz tell me.
Thanks in advance.
