           Summary: steam unable to launch games
           Product: Wine
           Version: 1.4-rc1
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED

After upgrading from 1.3.37 to 1.4-rc1, Steam is unable to launch a game.  This
occurs in both my normal prefix and a new prefix that I created.  When trying
to launch a game, Steam displays the normal dialog showing that it is launching
the game, but then the dialog disappears and nothing happens.  This is on
Debian wheezy AMD64 built with gcc 4.6.2-4.

This is the output to the console when trying to launch Team Fortress 2:
