And I can't get the filename without depending on KIconTheme, which I cannot (I'm trying to add a widget to KWidgetsAddons), so the approach of getting a QPixmap from QIcon is the only way.

Right now KIconLoader does two things (among others): 1) Lookup the right path to an icon from a given icon-name, and 2) actually read in that icon and return it as a pixmap of some form. It sounds to me like we want to be able to do *only* 1) here and then let KPixmapSequence finish the process by doing 2) with its own specific method? Maybe instead of loading a non-square icon we can instead add a method that returns the resolved path to an icon-name?
