After yesterday's updates, this bug reappeared for me in Precise 64-bit. It stopped affecting me for quite a while, but is back now. The only way I could get today's updates was to restart and log into a different desktop (Gnome).
Update manager was completely unresponsive in Unity. The Launcher icon would display a right-click menu but left-clicking an option in the menu brought no response. Left-clicking the icon also would not display Update Manager. I could find and select Update Manager in Dash, but left-clicking to select Update Manager brought no response. Perhaps unrelated, but the Menu Bar displayed 'Software Up to Date' while the Update Manager Launcher icon displayed 41 updates available.
