Wrong short time format in QLocale

The following code:

qDebug() << QLocale::system().dateFormat(QLocale::LongFormat);
qDebug() << QLocale::system().dateFormat(QLocale::ShortFormat);
qDebug() << QLocale::system().timeFormat(QLocale::LongFormat);
qDebug() << QLocale::system().timeFormat(QLocale::ShortFormat);

produces:

"dddd, dd. MMMM yyyy"
"dd.MM.yyyy"
"HH:mm:ss"
"HH:mm:ss"

Here the short time format is wrong (note the ":ss").
The settings under Windows 7 are:

Date (long): TTTT, TT.MMMM JJJJ
Date (short): TT.MM.JJJJ
Time (long): HH:mm:ss
Time (short): HH:mm
