When i try to join some servers my game crashes. My friends can join this servers but i can't 
I'm on a Linux Ubuntu 14.04 computer and my graphics cards is updated.
I try this things to fix and i keep getting errors:
Verify Game cache in steam
delete system folder and verify cache
delete KillingFloor.ini and verify cache
delete ClienRegistry.blob and Steamappid.txt and verify cache
Nothing Helps
Here is the log of Game start and crash:
