How do I start a Terraria server on Ubuntu 12.04?

Question

I installed Mono on my Ubuntu 12.04 server with the following commands:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list
sudo apt-get update
echo "deb http://download.mono-project.com/repo/debian wheezy-libtiff-compat main" | sudo tee -a /etc/apt/sources.list.d/mono-xamarin.list
sudo apt-get update

Here is my installation log:

I then used the simple command line of:

mono TerrariaServer.exe

And this is my server log:

$ mono TerrariaServer.exe

Please send crashlog.txt to support@terraria.org

I used to host a 1.1 server via Mono and it would crash occasionally. Any help with this would be well appreciated.
