I just found out that downgrading python-crpyto 2.1.0-1 to 2.0.1+dfsg1-5 solves the problem.
I will file a bugreport there: http://packages.debian.org/sid/python-crypto -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
