This doesn't work well with KGlobalSettings::singleClick() which reads from KGlobal::config() :-)

One solution then is to duplicate the readEntry, using m_componentData.config().group(...).readEntry(...)
Doing this with SkipMainComponentRegistration is 100% safe, it's just a bit of information duplication.

But I'd much rather have that than the checkKComponentData() + kstyleInstanceCount stuff.
Let's keep it simple, it decreases the amount of bugs :)
