[Wine] Steam shuts when clicking on a button

[Cr0k]

Hi there. 
I just installed Steam on Gentoo with wine-1.3.8 (i know, it's not the latest version, but i prefer avoid compilation, due to it's on a laptop), and when I click, i've got this error, and Steam stopped.


Code:
$ wine Steam.exe

Maybe I've to update wine to solve it? I just saw it in the changelog : 
  23872  Steam: Windows will automatically reopen after being closed

Thanks in advance
