It also affects me. I agree with the fact that it SEEMS to be triggered by Messaging, although I am not 100% sure. This is a very annoying bug, and only Atl+F2;r solves it. After updating to 3.6.2 problem STILL persists, and is seen while using Messaging Features. The tray freezes, closes, and an Empathy Chat Window opens. After this, the notification bar disapears untill restart of gnome-shell. (Ubuntu 12.10 gnome-shell 3.6.2)
