Here it is the log from a clean sandboxed wineprefix where I only installed game and update. http://pastebin.com/QNwK4xCC Here it is the log from the same wineprefix after winetricks -q d3dx9 d3dx9_43. http://pastebin.com/KNS3JfVF Both the segfaults happened when I tried to leave. I am not sure what I did differently before. But maybe the copy corrupts if started once without the correct locale. In both cases the execution command was: LC_ALL=ja_JP.UTF-8 wine griefsyndrome.exe Does it help?
