[Maemo] Scrollbar in QT has different color than in GTK (QPalette::BrightText color?)

See attached screenshots. The scrollbar in the settings is of blue color, while the scrollbar in my QT application is grayish white. The issue is not that apparent with the stock themes, as they use grey color for scrollbars (they do, right? I thought they use orange/blue, but it is grey now when I switched to them).

The problem seems to be that the QPalette::BrightText color doesn't get set properly from the theme. Its only my guess, but the bright blue color that is used for example for unread messages in the theme from the screenshots is in neither of the colors defined in QPalette.
