Server Crash on client connect

[duffyjp]

I've seen folks hosting TShock on a Raspberry Pi, so thought why not go deeper. I'll run a server on my 32bit PowerPC Mac Mini. Why not? I'm running up to date Void Linux.

Things start out promising, it fires right up, and quite quickly. I pick my world, settle my liquids etc.

$ mono ./TerrariaServer.exe

Terraria Server v1.4.1.1

Listening on port 7777
Type 'help' for a list of commands.

TShock Notice: setup-code.txt is still present, and the code located in that file will be used.
To setup the server, join the game and type /setup 4783314
This token will display until disabled by verification. (/setup)
: Server started

Unfortunately as soon as I connect it instantly barfs.

: 10.0.0.120:51789 is connecting...

Here's my mono info:

This is all in good fun-- I know it will be uselessly slow, but I have to wonder how this works on an 32bit ARM Raspberry Pi, but not a PPC. If there was some Intel native code in TerrariaServer it shouldn't work on a Raspberry Pi.
