I don't know when it was fixed, but it seems this bug no longer exists: I can launch Synaptic, and then launch Update Manager, without Update Manager complaining.
If you still experience the problem, please provide up-to-date steps to reproduce it. (We no longer show anything in the notification area for software updates.)
