I don't know exactly when it happens, but it has to do with the interaction of these two programs:

Unfortunately I have no idea what 242 means, but I would suggest placing print statements at various locations throughout your program to help narrow down where the problem is happening.

This is a bug. You can usually fix it by restarting your client/emulator, or server if you're in multiplayer.
