Were you able to test the video output using cheese?
Does the problem occur when using the current stable (0.3) or the SVN rev?

and too, I follow tutorial and put this under src/opencvWebcam.cpp
code:
int opencvWebcam::startCamera()
{
// capture =cvCaptureFromAVI("/home/rohananil/ggm2.avi");
capture =cvCaptureFromCAM(0);
if(capture==0)
return 0;
else
//
cvSetCaptureProperty(capture, CV_CAP_PROP_FRAME_WIDTH, 640);
cvSetCaptureProperty(capture, CV_CAP_PROP_FRAME_HEIGHT, 480);
return 1;

Did you try the latest SVN version from SVN?
I can't see why the use of cvSetCaptureProperty would make it working...

oh, sry the version with gtk is no longer in use. we just should clean the SVN
;)
the current SVN trunk is right here:

Any instructions on how to compile opencv 2.1.0 with v4l, gstreamer and jpeg2k?

Never mind, I got it working like this
sudo LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so qt-facetrainer
There is no direct access to the v4l libraries, one needs root priveleges for
qt-facetrainer to work. The above command allows that.
These instructions were found here:

I too have the segmentation fault when using SUDO:
sudo apt-get update
Face Verification Pluggable Authentication Module Started
Keep proper distance with the camera.
Verifying Face ...
Verification successful.
Segmentation fault
I removed the opencv and installed opencv 2.1, but then PFA would no longer
recognize my camera. I have since removed opencv 2.1 and gone back to the
dependency list given in the wiki installation page. Updated (detailed)
instructions for using opencv 2.1 that will maintain the camera use is needed
on the wiki, in my opinion.
