Yup, you shouldn't pull the plug on an open session and then try to synch.
In older versions of emplode, that activity would have given you really bad errors, at least in 2.0 it's got a nice clean message.
It warms the cockles of my heart to know that people are cycling the power just to look at Tux (even the sub-cockle area, for you Dennis Leary fans).
To save wear and tear on your power plugs, remember that you can get the player to reboot simply by sending or deleting custom logos with my logo editor.
