Dump from Steam crash

Not particularly sure how to debug, but both titles crash immediately after
loading the menu screen. I confirmed that r600g with the same mesa build on
another machine had no issues. Let me know if there are any relevant logs I can
provide

Details:
1.17.1 xserver
1.0.11 xf86-video-nouveau
68854.2372275 mesa-git
4.0rc4 linux-git

Only relevant line in dmesg:
[ 6389.605899] streaming_clien[6094]: segfault at 0 ip 00000000f75ee410 sp
00000000ffe6c9d0 error 4 in streaming_client[f7576000+195000]
