Zero-k does not start on linux

I have changed my system to linux not long ago, and decided to try zero-k again. I have installed it following the instructions on the download page, but after i try to launch any mission or multiplayer game, no mission is actually started.

In terminal, there is an exception stack that looks like this:

What is wrong or what should i do to launch and play the game?
P.S. my system is ubuntu 13.04, if that matters

Amazingly, that fixes problem partially. Spring starts.
however, after the load sequence, spring window closes right at the moment where the game should begin.

Use the official drivers provided by Nvidia instead of nouveau.

quote: forgot the exec permission bit for the shipped spring binary.

This. I spent 2 hours compiling 91.0 only to find out that ticking a box in the static build would have worked.
