I think I finally figured out what you're trying to do, and it's
already supported in KConfig. You can have an "anonymous" config
object. I think using that feature of KConfig would be better than
working with invalid groups, because KConfigGroup is meant to be used
only as a part of a config object. I don't think I documented how to
open an anonymous object, so here it is; KConfig(QString(),
KConfig::SimpleConfig)
