GMod dedicated server on ubuntu segfaults on crash

I am running a Garry’s mod server with CSS mounted on an ubuntu 14.04 server.
When I run a CS:S server, there is no problem, it all starts correctly and I can play on it, however, when I start the GMod server like


./srcds_run -game garrysmod +maxplayers 12 +map gm_flatgrass

it outputs this in the console


g:~/steamcmd/serverfiles$ ./srcds_run -debug -game garrysmod +maxplayers 12 +map gm_sandbox -console
