QLocale: conversion from QString to int fails if the string contains a positive sign and separators

QString dString( "+100,000" );
int dInt = locale.toInt( dString, &isOk );
qDebug() << "dInt is " << dInt;

--> Error: QLocale::toInt(..) returns 0 if the QString contains a positive sign '+' and a separator.

The attached example application demonstrates the use case.
