Log from Steam installation

I've tried to test some of my old bugs in Steam so I launched it and it crashed
a couple of seconds after the Steam window, "Steam Update News" window and
"Install Gecko engine" dialog appeared. So I removed ~/.wine directory,
downloaded a new SteamInstall.msi, installed it and when I tried launching it,
the same thing happened.

I think this bug may be related to the Gecko engine not being able to install
itself. I've attached log from Steam installation and from its launching.
