Comment 11 for bug 404525

Sorry, I wasn't clear. I was checking to make sure that it had not changed behavior in Karmic (I'm away from my laptop for a bit).

I believe Ubuntu is currently blocking the exact bubble you are requesting since they think it is redundant (the icon should change in gnome-panel).

Once we finish cleaning up the strings we can revist whether the bubble is redundant.
