QFileDialog::getOpenFileName and getSaveFileName not showing properly on S60 emulator

I tried using the QFileDialog with Qt 4.7.0-rc1 on S60, but it looks absolutely awfull, and is unusable for me in its current state (see attachment). Problems show up using getOpenFileName, and getSaveFileName. Switching between landscape and portrait may at times result in a better screen, but usually doesn't fix it completely, and is just as likely to make things worse. Note that i do use a custom stylesheet which does not yet cover all the items which are present in QFileDialog.
