Execution log with WINEDEBUG=warn+all

I am still suffering a failure for Wine to load Steam with the 03 Dec 2013
update, even after building the latest version of Wine from the git repository
(with the fix for bug 35030). Steam is installed in a 64-bit Wine prefix and
was working properly prior to the update.

Steam is still failing during log-in (although with slightly different messages
than with the 1.7.7 release). It loads in offline mode without problem.

I have tried installing Steam to a fresh WINEPREFIX from the downloaded
executable. It consistently fails after entering the Steam Guard authentication
code.

I have attached a log, run with WINEDEBUG=warn+all.

My Wine version shows as follows:
user@mithra:~/Documents/git/wine-git$ ./wine64 --version
wine-1.7.7-160-g58d96f7

Thanks for the help!
