Another item to test: you could try just placing the Preview widget directly into the UI without embedding it within a QScrollArea widget. I kind of get the feeling that if this is a memory overrun or a clipping error, it'd be more likely to happen closer to the widget with the actual image data. I kind of doubt that QScrollArea would be so sensitive to the physical size of the image...

BTW, on kinetic scrolling: it seems you can enable kinetic scrolling on most any Qt Maemo widget that can scroll. You can manipulate this feature (turning it on or off, retrieving various scrolling info, or messing around with it in general) by accessing the "kineticScroller" property of the widget. For example, this would switch on kinetic scrolling for a widget called "scrollArea":

Code:
 QAbstractKineticScroller *scroller = scrollArea->property("kineticScroller").value<QAbstractKineticScroller *>();

 if (scroller)
     scroller->setEnabled(true);
There's a bunch more info in the Qt docs about this.
