--- Comment #6 from Andrew Eikum aeikum@codeweavers.com 2012-09-04 12:48:00 CDT --- There's nothing really suspicious in there. Are you presented with a backtrace in the crash dialog or in your terminal output? Another log with the same channels and also "+seh,+timestamp" might give more info. If you've got time, doing another bisect might be useful, as I think something went wrong with the one you did earlier (winecoreaudio isn't compiled on your system, so it can't be the bad commit).
