AVT Cameras segfault (use of flag CV_CAP_PVAPI) (Patch #1771)

I build opencv WITH_PVAPI flag and install it on my Linux Xubuntu 11.10 (x86_64) with 3.0.0-17-generic linux kernel.
My camera is Manta G-032, I tried put it to work with opencv using the below example program:

 1#include <stdio.h>
 2#include <opencv/highgui.h>
 3
 4int main( int argc, char** argv )
 5{
 6    cvNamedWindow("Example", CV_WINDOW_AUTOSIZE);
 7    CvCapture* capture = cvCreateCameraCapture(CV_CAP_PVAPI);
 8    assert(capture != NULL);
 9    IplImage* frame;
10
11    while(1)
12    {
13        frame = cvQueryFrame(capture);
14        if(!frame) break;
15        cvShowImage("Example", frame);
16        char c = cvWaitKey(13);
17        if(c == 27) break;
18    }
19    cvReleaseCapture(&capture);
20    cvDestroyWindow("Example");
21    return 0;
22}

The result of this program is a segfault. After of navigate on google and analyse the codes cap_pvapi.cpp from opencv and StreamAndGrab.cpp from AVT GigE SDK code I can solve the problem.
On PvAPI of opencv is missing a 'memset' of structure tCamera as StreamAndGrab.cpp code.
I put the follow line: memset(&capture->Camera, 0, sizeof(tCamera)); just after of object CvCaptureCAM_PvAPI creation.
