I have Ubuntu 13.04 64-bit installed. I also have steam installed. Steam launches normally each time but every time I search Team Fortress 2 it loads for a short time and then closes automatically. I went "Google is my friend". I couldn't find any answers that are related to my problem. Here's the log:
