--- Comment #17 from tom+bugs.winehq.org@falkensweb.com --- I wont be the last person to find this on Google. Was there any update ?
I still get this on Ubuntu 14.04 with Wine 1.7 from the official PPA.
Renaming both ~/.wine/drive_c/windows/system32/MUI and ~/.wine/drive_c/windows/system32/mui stops the crash on save game load. And also makes the game start many times faster over all.
