three.js share a geometry for lines and particles

I would like to use one geometry object for some fancy particle animation and display lines between those particles.

geometry = new THREE.Geometry();

particles = new THREE.ParticleSystem(geometry, particleMaterial);
line = new THREE.Line(geometry, lineMaterial, THREE.LinePieces);

Somehow the Line Object is not rendered in the scene, but the particles show up.

With WebGLRenderer you can't share geometry in some specific situations. Best option is to do geometry.clone().

Here's the jsfiddle fixed: http://jsfiddle.net/Pk85y/3/
