It also asserts in RapCAD, so my diagnostic must be wrong.
The next guess is that this is exported from SketchUp and it's not actually a closed volume.
OpenSCAD requires imported models to be closed, manifold meshes.

Perhaps a mesh repair tool (meshlab, netfabb) would help?
Getting the original SketchUp model and looking for issues in it might also help.
