[Wine] Steam crashes after login - any troubleshooting t

[new Thrall]

The Steam client crashes after I login. After submitting my credentials, Steam displays a dialog box informing me the client is 'connecting'.  I then see the Steam main page and a blank news page displayed for roughly a second or so before the client crashes.

I'm running Ubuntu 10.10 maverick which I've installed on a usb flash drive using a capser-rw file for persistence.

wine-1.3.14

I'm not sure how to troubleshoot.  How do I identify if the problem is with wine or steam or the video card driver, or what?  Any ideas?

motherboard: ECS Elitegroup 945GCT-M
sound: integrated audio
video: ATI Radeon X1950
