If you launch it with STEAM_RUNTIME=0 steam does it still crash? Could you provide your steam’s system information if it does.

Launching with STEAM_RUNTIME=0 produces the following error regarding missing llibraries: https://gist.github.com/kvsm/86594a0d663f73fdd9b1

And here is my system info: https://gist.github.com/kvsm/16bde028a623d31ad7cb

Hmm, and you have ia32-libs installed?

Do you see any output with CrashId= listed?

Can you paste the contents of the output of Steam->Help->System Information, including the part at the bottom listing crash reports?

Thanks.
