Do you have notify or timecodes enabled in config.ini? They don't seem to go well with empty playlist, with the same symptoms. If so, try to kill the player with Ctrl-C from the serial port. If you are fast enough, you will manage to drop to the shell. If not, you will have to downgrade to 1.03, edit config.ini, then reaply 2.0b3.
