Indeed that's what it does:
- to "load" the settings it just calls KIconTheme::current()
- when saving, it writes it to kdeglobals, then deletes the icon cache, calls
KIconTheme::reconfigure() and emits changed signals.

I suspect this is a problem in kiconthemes then, e.g. that it doesn't correctly
reload the settings.

I suppose that kiconthemes does that because it doesn't notice the settings
change...
