Steam through Wine stopped working for me yesterday. After starting up it would just quit.

According to http://bugs.winehq.org/show_bug.cgi?id=35030 it's fixed in 1.7.8. Sadly the latest version on homebrew at the current time is 1.7.7. Let's fix it!

`brew edit wine`

Update the 'devel' section:

```
  devel do
    url 'http://downloads.sourceforge.net/project/wine/Source/wine-1.7.8.tar.bz2'
    sha256 '30e17f5f863a09416f3d229666566b318dbb40f683d4ca6630012c60bb511804'
    depends_on 'little-cms2'
  end
```

Then upgrade wine:

`brew upgrade wine --devel`

That's it!

Caveats:
- Remember to kill your existing wine processes (ps aux | grep wine) after installation
