I think this > wine: Call from 0x7b8425a0 to unimplemented function ntoskrnl.exe.KeInitializeMutex, aborting means it's trying to load something that requires direct kernel access. At least, that's what I got from googling KeInitializMutex and trying to decipher http://msdn.microsoft.com/en-us/library/aa490233.aspx . I don't think that's something you can fix on your own, though someone with more expertise may be able to help you. (This is definitely way beyond my level.) You should probably file a bug report.
