Fixed.

I guess I didn't get enough sleep the last few days and created a pretty creative error.

Everything worked for me as long as I didn't restart Poser. That rarely happens here, because Windows with active Poser runs in a virtual machine on a separate server and is rarely shut down. Except when I brought Poser to a halt using Python :) And that's exactly what happened, after which this script here suddenly stopped working for me too and I got a chance to find the error.
