Changing style => objects disappear

[donaldaugustsson]

i have imported a object from the 3D-warehouse and when i change style the object disappear. Its visible in all styles with "colors" but when your change to "hand-made" sketch-look-alike-styles it disappear... why?

(i can post the skp-file but its quite big...)

What happens if you turn on View/Hidden Geometry, and then Zoom extents? I think if the edges have been hidden, you could get this result when using a sketchy line style.
