--- Comment #1 from James Carthew jcarthew@gmail.com --- I suspect this may be caused by the use of a new unique texture format as described in here: http://wiki.dark-omen.org/do/DO/Sprite_Format. The game will only partially work on an X11 server running in 16-bit mode. In 32-bit mode the game fails to load at all. This error has been present since at least wine 1.34.
