OpenCv Problem

[danics]

Hi every body!

i m using Qt and Opencv 2.0 for create a program that give a image and do color segmentation on it!
but my problem is a signal error that i give from some opencv methods like cvKmeans2 and cvCvtColor!
(disassembler for cvCvtColor is 0x1002e4e4 movdqa %xmm3,-0x38(%ebp))
if i add this functions in another C++ application like Visual C++ it works fine or in Qt if i dont use QApplication i havent any error please help me!

nobody can help me
i think it is for Assert function
this is my code i have got a signal error on cvKmeans2 in Debug mode and i cant enter this function with step into too
<code>
loginfo += "\n\nCalculating Image Segmentation algorithm with Kmeans";

CvMat *arr =cvCreateMat(im->height*im->width, 1, CV_32FC1 );
CvMat *retVect =cvCreateMat(im->height*im->width, 1, CV_32SC1 );
//cvCvtColor(im, im, CV_BGR2HSV);
int *colorArr[3];

for(int i=0; i<3;i++)
colorArr[i] = new int[cluster_count];

for(int k=0; k<cluster_count; k++)

cvReleaseMat(&arr);
cvReleaseMat(&retVect);

cvDestroyWindow("Clustered");

cvReleaseImage(&toShow);

please help me
