ImportError: /lib64/libavcodec.so.54: symbol avpriv_update_lls, version LIBAVUTIL_52 not defined in file libavutil.so.52 with link time reference

I have installed OpenCV on Fedora 17, and it gives me this error after i try to import cv2 in Python:

Python 2.7.3 (default, Jul 24 2012, 10:05:38) [GCC 4.7.0 20120507 (Red Hat 4.7.0-5)] on linux2 Type "help", "copyright", "credits" or "license" for more information.
