QTableWidget crashes on setItem

[Raccoon29]

I everyone,

I'm trying to fill a QTableWidget with some items, but when trying setItem it segmentation faults.

// vLastId is a ID int
    // n becomes 2
    // query is valid
    int n=viewport->db->Count("customer_addresses a,contacts c",
        "c.id_customer=a.id_customer AND c.id="+QString::number(vLastId));
    QSqlQuery query=viewport->db->Select("a.id,a.ragsoc","customer_addresses a,contacts c",
        "c.id_customer=a.id_customer AND c.id="+QString::number(vLastId));
 
    // two columns defined elsewhere
    ui.tbwcaddresses->setSortingEnabled(false);
    ui.tbwcaddresses->setRowCount(n);
    int row=0;
    while(query.next())
    {
        CTableWidgetItem *zid=new CTableWidgetItem(query.value(0).toString());
        ui.tbwcaddresses->setItem(row,0,zid); // this row fails and throws exception
 
        CTableWidgetItem *iragsoc=new CTableWidgetItem(query.value(1).toString());
        ui.tbwcaddresses->setItem(row,1,iragsoc); // this doesn't fail, and seems the same operation!
        ...
        row++;
    }
    ui.tbwcaddresses->setSortingEnabled(true);

// vLastId is a ID int
    // n becomes 2
    // query is valid
    int n=viewport->db->Count("customer_addresses a,contacts c",
        "c.id_customer=a.id_customer AND c.id="+QString::number(vLastId));
    QSqlQuery query=viewport->db->Select("a.id,a.ragsoc","customer_addresses a,contacts c",
        "c.id_customer=a.id_customer AND c.id="+QString::number(vLastId));

    // two columns defined elsewhere
    ui.tbwcaddresses->setSortingEnabled(false);
    ui.tbwcaddresses->setRowCount(n);
    int row=0;
    while(query.next())
    {
        CTableWidgetItem *zid=new CTableWidgetItem(query.value(0).toString());
        ui.tbwcaddresses->setItem(row,0,zid); // this row fails and throws exception

        CTableWidgetItem *iragsoc=new CTableWidgetItem(query.value(1).toString());
        ui.tbwcaddresses->setItem(row,1,iragsoc); // this doesn't fail, and seems the same operation!
        ...
        row++;
    }
    ui.tbwcaddresses->setSortingEnabled(true);

To copy to clipboard, switch view to plain text mode 

If I bypass the excepting row, the second setitem works well.
I've done this operation tons of times before, but never this problem... What could it be?

Thank you in advance

did you create a test application for this table and try to insert items?

No I didn't, because I found the fix: there was the usual SLOT called by cellChanged that did controls before it should. Sorry, thank you anyway for your help. It seems like qtcentre air is enhough to solve problems
