OpenCV 3.0.0 error with Gstreamer

I just installed OpenCV 3.0 following this tutorial:
http://rodrigoberriel.com/2014/10/installing-opencv-3-0-0-on-ubuntu-14-04/

I didn’t encounter any error during the installation process. However, when I tried running the a sample program such as the following,

cd cpp/
./cpp-example-facedetect lena.jpg // (../data/lena.jpg) OpenCV 3.0 beta
./cpp-example-houghlines pic1.png // (../data/pic1.jpg) OpenCV 3.0 beta

I get the following error:

Processing 1 lena.jpg
GStreamer: Error opening bin: Unrecoverable syntax error while parsing pipeline lena.jpg
Capture from AVI didn't work
init done 
opengl support available 
In image read

I’m a complete newbie to computer vision and I don’t have a clue as to what the problem could be. Could anyone help me out?
