I tried in gnome-terminal with Code: wineconsole "C:\Programme\Google\Google SketchUp 8\SketchUp.exe" and it opened a cmd window which opened SketchUp, but putting the above command on SketchUp's ruby console still freezes SketchUp and gives the same error in gnome-terminal. I also started directly cmd.exe and launched SketchUp.exe from there, but same result.
