QLabel displays '&' if it has a buddy and focus policy is set to Qt::ClickFocus

In the form below, preview it with Designer and click on the label. A '&' character will be inserted in the QLabel. This has been confirmed in Qt 4.3 and 4.4.0. The same behavior happens with hand-written code (i.e. no use of Designer).
