Created attachment 49775 [details] terminal output - 20.10.2014
Application tried to create a window, but no driver could be loaded. The explorer process failed to start.
Seems suspicious. Does using the X11 driver instead of the Mac driver (see http://wiki.winehq.org/UsefulRegistryKeys) make a difference?
