Looking at bug 5721, the final comment has found the problem that causes this. The original issue in the bug is fixed, but a new one cropped up. Basically if the user doesn't have r/w access to /dev/input/event* then wine segfaults. What should happen is that wine should print an error on the console about it so that users that read the console output can fix this problem.. I dont know of the risks of allowing global r/w access to /dev/input/event* so maybe the error shouldnt necessarily say that, but if there are no problems with giving global r/w then it could say that..
