QDoubleValidator accepts numbers with thousand-separators despite the docs says it doesn't.

#include <QString>

int main( int argc, char* argv[] )
{
  QApplication a( argc, argv );

  QString input = "1.000.000,50";
  int pos = input.length()-1;
  QObject o; // dummy
  QDoubleValidator v( &o );
  QLocale loc(QLocale::German,QLocale::Germany);
  //loc.setNumberOptions(QLocale::RejectGroupSeparator);
  v.setLocale(loc);
  qDebug()<<"Decimal :"<<v.locale().decimalPoint();
  qDebug()<<"Group separator :"<<v.locale().groupSeparator();
  QValidator::State s = v.validate( input, pos );
  qDebug()<< "Validator result: ";
  switch ( s )
    {
    case QValidator::Invalid:
      qDebug()<<"Invalid";
