I've given up on Poseidon. Besides the geometry bugs, it just seemed like there were too many bells and whistles I wanted to use which weren't available. For example, when composing my deployment model, the only UML symbol which I could place within a node was another node. and I wanted components within my nodes.
I've switched to Sparx Enterprise Architect which is looking very handsome right now.
Components in a UML 2.x Deployment diagram are not directly used by nodes. The type-level depiction of components occurs in the Component diagram, and the instances of these components are used by the Deployment diagram. This is most often done with the use of artifacts.
