After all it was a misconfiguration of my system and not a problem of Python or Django.
Somehow the special files /dev/random and /dev/urandom got screwed up. I suppose it was the outcome of a bad update of the udev package on my Archlinux system. When I recreated the node of /dev/urandom manually the random.SystemRandom().randrange returned all numbers instantly.... Thank you for pointing me to the right direction.
