getExistingDirectory() duplicate keyboard accelerator

When invoking QFileDialog::getExistingDirectory() there are buttons &Choose and &Cancel; it is bad practice to have duplicate keyboard accelerators like this.

In :const char *QDialogButtonBoxPrivate::standardButtonText(QDialogButtonBox::StandardButton sbutton) const

There is a case that looks like this:

case QDialogButtonBox::Cancel:
buttonText = gnomeLayout ? QT_TRANSLATE_NOOP("QDialogButtonBox", "&Cancel") : QT_TRANSLATE_NOOP("QDialogButtonBox", "Cancel");

Meaning that if you are using a gnomeLayout for your dialogs, and you use a QFileDialog::getExistingDirectory(), then there will be 2 "C" keyboard accelerators.
