Lines 458 to 459 in 6a623a9

	str = str.replace(",", QLocale::system().groupSeparator());
	str = str.replace(".", QLocale::system().decimalPoint());

Must be:
str.replace(".", ":"); // to catch the case where group and decimal separators are exchanged
str = str.replace(",", QLocale::system().groupSeparator());
str = str.replace(":", QLocale::system().decimalPoint());
