Have you checked the WineHQ AppDB for your program? Maybe it will contain some useful information that can help you on your way. If not, try the following. That line of output is probably unrelated, which means we have no output to go on. You may have to enable some debugging channels to get more output, see http://wiki.winehq.org/DebugChannels . I'm not sure which channels you should enable since you didn't state what the game was, but try any of the keyboard/input ones and see if it outputs a bit more about those now.
