No, that's not the bug I refer to. The one I refer to is the one where all front-panel input and IR input is completely locked out (known bug in beta7). When that happens, the ignition-sense command (which is also just an "input" to the player) is ignored and the player keeps playing when you pull the key.
Your bug describes being able to use the top button to sleep the player, so you're talking about something totally different. In fact, I've never heard of your bug before, and it surprises me. Have you talked to Hugo about it?
