[SOLVED] Steam troubles. Segfault after login.

Question

Hello. I'm usually pretty good about solving my own problems, but this one has me beat. So, yay, first post.
Recently my nephew brought me his computer for a nuke and pave, and since he doesn't have a legit Windows key and I don't use Windows anymore I decided to install Arch on his machine, since it's what I use and I'm their go-to tech support.
Unfortunately I'm having trouble getting Steam to run correctly on his machine. It will start up, update/verify install, show the login screen, and after authenticating it promptly dies.
Some details:
This is a somewhat fresh install. I provisioned it from within a Vbox VM on my own workstation and then moved the HDD to the actual box.
Full system update was done just today. Problem existed prior and persists after.
Proprietary GPU drivers are not being used.
lspci shows the video adapter to be: 07:00.0 VGA compatible controller: NVIDIA Corporation G71 [GeForce 7900 GS] (rev a1)
I've already removed Steam's bundled libs, as per the wiki.
I've tried steam --reset and rm -rf ~/.steam and removing and reinstalling the steam package. No dice.
The presentation of problems detailed here seemed pretty similar so I installed lib32-dbus but this did not resolve the issue.
I'm not checking remember password. This bug seems to be unrelated

I then tried DEBUGGER=gdb steam and besides the identical output above and the expected gdb messages I get
Program received signal SIGSEGV, Segmentation fault.
0xf6d9eab8 in ?? () from /usr/lib32/xorg/modules/dri/nouveau_dri.so
So then I tried native runtime STEAM_RUNTIME=0 steam with the help of the alucryd-multilib repo. The output seems to be identical to the above. Output of DEBUGGER=gdb STEAM_RUNTIME=0 steam available here.
Throwing that into Google yields nothing of interest that I can find.
Perhaps hardware failure? But my nephew played Dust AET for a while and it ran fine.
I'm at a loss.

I'm also in a similar situation, surprised that it took this long for someone to post the problem here (it's been at least a week since this started)...
There's a report here:
https://github.com/ValveSoftware/steam- … -67916730\
I also get a segfault when running steam with STEAM_RUNTIME disabled now.
Here's my command line output: https://gist.github.com/uberscientist/0 … 26de094ec5
With STEAM_RUNTIME libs it runs fine (however TF2 fails to start...)
If I can provide any more useful information let me know. I am running Arch Linux, systemd (so OpenRC probably has nothing to do with it), x86_64.
I'll subscribe to this topic and continue crossing my fingers an update fixes things.
