@Kevin: One could also just do -

bool addedDefault = false;
for ( ... ) {

    if (l == QLocale())
       if (!addedDefault) {
          addedDefault = true;
       }
       else
          continue;
    
    ...
}

Or we could just add the default one in the beginning/end. Let me know which you prefer. I've already implemented the default swapping one.
