The attached demonstrates a rather pervasive memory leak in the Qt UI support on Symbian. (The leak may be on other platforms as well, but can't test on other platforms since they don't have a way to check heap size.)
I've filed Qt bug 11777 for this. If anyone else thinks it's important they can "vote" for it.

I've identified the bug as a problem in QAbstractScrollArea: It fails to do an "ungrabGesture" in its destructor to mirror the "grabGesture" done during creation.
