I had the same problem. By pressing shift or caplock the MagicKeyboard wouldn't work anymore.
It turns out that the problem comes from the fact that I use the keyboard on both ubuntu and windows (dual boot). When I connect the keyboard on ubuntu, it no longer works on windows because the keyboard and ubuntu share a sync key that windows does not know. When I associate the keyboard on windows, it still works on ubuntu (when it shouldn't) until I press caplocks. In fact, I think the bug is that the keyboard works a bit under ubuntu while the key is not good, if it returned an error we would find the problem right away. To solve the problem, I reassociated the keyboard with windows and then I copied the connection key and I copied it in the bluetooth configuration of ubuntu. Since my two OS share the same connection key for the keyboard, I don't have any more problems between the two OS and Capslock works well.
