Had everything working and games running decently, last client update broke for me.

Here's what I get when running in terminal:

The crash says you have ATI Radeon HD 5800 Series graphics card. What driver version do you have?

Please try this:

exit steam completely, open a terminal window, and start steam this way:

STEAM_RUNTIME=0 steam

And post back here the results.
Thanks.

How to you figure out the graphics card from the terminal output?

It would be definately good to know which card you are using what driver and how you installed it.

Steam window shows up and client updates but then it crashes again.

Drivers are fglrx experimental beta, there are three options in additional drivers whereas there was only two when I remember putting it on.

Have you changed/updated your graphics card drivers recently?

Can you try installing the latest stable graphics drivers and see if there is any change?
