[MC-103550] Malformed ping packet from server crashes client

I was working on a small side project, and wanted to send the motd.
I made a small mistake, and forgot to delete a part of it.

After that, my game crashed. When I tried to start the game up, it crashed immediately after clicking the 'multiplayer' button.

This kept happening until I deleted the servers.dat file, or removed the icon field from the nbt.

Status response packet I sent:

};

The problem is in it that I sent data:image/png;base64, twice.

I hope this will get fixed, since it's not a good thing that servers can prevent users from playing Minecraft multiplayer

Thanks,
