Symbian: QScrollArea makes the widgets overlap on Nokia E72

I'm trying to create a dialog that's larger than my E72's landscape screen and I'm using a scroll area to make the dialog scroll vertically.

This approach works on touch phones, but not on the E72, where the widgets start overlapping as soon as I scroll past the bottom of the screen. The QDialog contains a QScrollArea which contains its default "contents widget". This widget contains a form layout with a bunch of line edits, combo boxes, labels, etc.

P.S: Don't know if you've noticed, but there's a "hole" in the soft key bar and you can see widgets through it.
