Issues while generating a view with QStandardModel,QStandardItem & QTreeview

/*creating an QStandardItem & appending 2 new QStandardItems such that

QStandardItem* MainWindow::createNewCRListItem(const QStringList &sList)
{

QIcon lIcon(":/images/contact.png");

cll.setText(str);
qDebug()<< str;
}
}
nameItem->appendRow(&cyName);
nameItem->appendRow(&cll);
//emit nameItem->emitDataChanged();
return nameItem;
}

/* get a QList<QStringList> from parsing object
create a QStandardItem (above func)
set that QStandaradItem to a QStandardModel
later .. set the QStandardItem to QTreeView as shown below
*/
void MainWindow::getlistFromParse( parseClass &pObj)
{

list = pObj.getList(); //return the reference of list
int modelSize= list.size();
int itemRow;
qDebug()<< "Row cont "<< modelSize;
crItemModel.setRowCount(modelSize);
qDebug()<<"check row: "<<crItemModel.rowCount();
crItemModel.setColumnCount(1);
qDebug()<<"check col : "<<crItemModel.columnCount();

QList<QStringList>::const_iterator i;
for(i=list.constBegin(),itemRow=0;i!=list.constEnd ();itemRow++,i++)
{
const QStringList& subList=*i;
QStandardItem *item= MainWindow::createNewCRListItem(subList);

crItemModel.appendRow(item); //application closing unexpectedly
//crItemModel.setItem(itemRow,1,item);
}
}


while the stack trace shows segmantation fault in crItemModel.appendRow(item);
crItemModel is of type QStandardModel
and


tree = new QTreeView(parent);
tree->setModel(&crItemModel);

Think about scope:

QStandardItem cyName;
QStandardItem cll;

I am so stupid on this.
Thanks a lot.
