Comment 33 for bug 1257734

Wine 1.7.8 is not fixing this bug for me. I have frequent authentication failure hangs. When I first install steam I can get in but can not download any games or verify the game cache.

After I log out of steam, logging in again causes steam to fail during authentication.

Interestingly I get the same error prior to the 1.7.8 fix,
[1215/013422:ERROR:resource_bundle.cc(417)] Failed to load C:\Program Files (x86)\Steam\bin\chrome.pak
Some features may not be available.

Just as a sanity check
wine --version
