Error in QSqlTableModel inherited table - c++

Question

I have this class that inherits from QSqlTableModel and it brokes after calling the submitAll() slot, after calling insertPoint some times. Here is the code.
Thanks for the help.
Regards.
#ifndef VWLANDMARKTABLEMODEL_H
#define VWLANDMARKTABLEMODEL_H

if(!q.exec()) {
setLastError(q.lastError());
return false;
}
qDebug()<<"hola mundo";
return true;
}
void VWLandmarkTableModel::setDefaults(int row, QSqlRecord &r)
{
r.setValue("IdImage", idImage());
r.setValue("Name", "Unnamed landmark");
r.setValue("Username", username());
}

The problem was in my custom select. Calling setFilter() causes a infinite calling loop
