wine users - Feb 2012 - dungeon defenders stopped working after game update

After a steam and dungeon defenders update, the game stopped working with a
crash at start time. These are the relevant messages, tested with wine 1.4 rc5.
Suggestions?

Make sure that ntlm_auth >= 3.0.25 is in your path. Usually, you can find it
in the winbind package of your distribution.
Install winbind.

Reinstall your graphics drivers. If your system is 64 bit, make sure you have 32
bit opengl installed.

sorry, the errors above where due missing nvidia drivers. However, the game
still dies quite silently. All I get after starting the game is:

fixme:winhttp:WinHttpDetectAutoProxyConfigUrl discovery via DHCP not supported

err:ole:RevokeDragDrop invalid hwnd 0x2014a
err:ole:RevokeDragDrop invalid hwnd (nil)

Second runs return nothing at all. What can I do to figure out why the game is
dying silently?
