Terraria under Ubuntu 14.04 - crash upon map loading

I just installed the beta version of Terraria for linux which just came out. I'm very happy the developers decided to make a linux port for this game. Of course the port is full of bugs and we're supposed to be reporting these bugs. Except I can't post my issue at the terraria forums right now (I'm not exactly sure why). So instead I'll post it here in case it can help someone in any way.

I just ran steam off of the command line, where you can open steam by going to

~/.steam/bin32/steam

and running

$ steam

from there you should be prompted to enter your credentials. From this point on just open another console window and go to

~/.steam/steam/SteamApps/common/Terraria

and run

$ ./Terraria

At this point I can basically start my game, I created my world and all looked OK. Once I tried to play it, the screen loaded for a second and then the game crashed. The following message was shown in the console:
