Thank you so much - I was such an idiot (see below).

Still not. I was about to prove it and already uploaded the file, when I
saw, what was really going wrong ...

This is THE crucial point. If I just delete the Py_CLEAR-line, everything is
working smoothly and calling PyFloat_FromDouble-is working too.

Again: Thanks a lot. 'Reference counting' won't become one of my
hobbies ;-).

Best,
