Comment # 75 on bug 1068792 from Dave Plater

Actually you can just delete them one by one, OpenCV plugins:
/usr/lib64/frei0r-1/facebl0r.so
/usr/lib64/frei0r-1/facedetect.so

and gavl plugins:
/usr/lib64/frei0r-1/scale0tilt.so
/usr/lib64/frei0r-1/vectorscope.so
/usr/lib64/frei0r-1/rgbparade.so

Thanks.
