Same here, a GDB log of the crash is below. I think it was because I had p11-kit 0.20.1-3, but libp11-kit 0.20.3-1. I fixed it by running:
sudo apt-get install p11-kit=0.20.2-5 p11-kit-modules=0.20.2-5 libp11-kit0=0.20.2-5 Jim ------ $ gdb python --args python -c "import cv2" GNU gdb (GDB) 7.6.2 (Debian 7.6.2-1) Copyright (C) 2013 Free Software Foundation, Inc.
