In Kubuntu Linux versions 14 and 15.10 My game crashes when i click open for lan, Or in multiplayer if i connect to another server using connect or connect with IP.
All drivers are the latest. Firewall on or off makes no difference.
Also this is the non steam version of the game fully updated.
These are the error logs.
