Have you run the client from different users?
@gdrewb-valve Just now tried that, still has a segmentation fault.
I'm getting a similar crash:

Sorry, had you run the client as different users in the past, before you started getting the segfault? There's a Steam startup bug that is triggered when Steam is run by different users. It is avoided by rebooting inbetween Steam sessions. The next client will have a fix, but it may or may not be your issue.
@Steve4448 Can you get us your config information we ask for here: https://github.com/ValveSoftware/steam-for-linux#reporting-issues
The crash is in fglrx_dri.so...make sure you're running the current AMD video drivers recommended for your AMD card.
@Steve4448 ...or as much information as you can get even if Steam can't start up. Information from glxinfo would be useful.
@gdrewb-valve I've never ran it on another user before this started happen, no.
@bdeen-valve Sorry for not following that convention, wasn't aware of this. I've edited the main post to include some related system information, if you need anything else just mention it.
I'll attempt to try out different ATI driver packages and see if that solves the issue, thanks for the tip.
EDIT: I've reverted back to the non-experimental proprietary driver, after a few issues related to the driver I finally got it displaying things properly (broken multi-monitor support now -.-) steam starts properly now. I'm going to continue trying out different builds still. I apologize but I wasn't able to run glxinfo before I did this.
I've re-installed the experimental drivers once again, assuming that it wouldn't work it apparently works perfectly fine... Interesting...
@Steve4448 Given the callstack in the crashes you reported, they're all in fglrx_dri.so, so you've probably resolved the issue here.
Nothing extracted yet.
A few days ago if I remember correctly before the latest update Steam has been working fine for me, then it started not opening (as it's having a seg fault). I've ran it via a terminal and the following happens: http://paste.ubuntu.com/1685229/
I've completely purged the steam install, deleted the steam folders at ~/.steam and ~/local/share/Steam and re-downloaded, re-installed, same issue.
Computer information:
OS: Ubuntu 12.04 (64 bit, kernel 3.2.0-38-generic), gcc version 4.6, Xorg version 1.11.3
CPU: Intel Core 2 Quad Q8200 @ 2.33ghz
GPU: ATI Radeon HD 6850
I'm using the proprietary FGLRX graphics driver (experimental beta).
