Yep, it looks like we're getting a player with a NULL state somehow,
which is crashing when we try to convert that into a variant for sending
over the bus. (1) we should sanitize our inputs better, ie modify the
state property setter to disallow NULLs. More importantly, (2) we need
to figure out where this NULL state is coming from.
