The output winedebug: http://paste.pocoo.org/show/542938/
This log is using an out of date version of Wine. The problem is these lines:
0027:err:ole:CoInitializeEx Attempt to change threading model of this apartment from multi-threaded to apartment threaded 0027:err:dsound:devenum_thread_proc CoInitializeEx failed: 80010106
Those have been changed in 6d391df4aaefaef1e13ff2dd3571f96fdff6405d, which is in Wine 1.4-rc1, so the problem might have been fixed by that commit.
I'm not very familiar with Gentoo. Can you make sure you're testing with 1.4-rc1 and try again? If it's still a problem, gather another log.
