No, QCoreApplication doesn't know anything about rc files, it has to be 
something else; i'm not saying the migration being done after/before 
QCoreApplication is not the trigger, i'm just saying that your theory can't be 
the reason.

Also it'd probably make sense for you to involve the kde-frameworks mailing 
list, more knowledgeable people about kconfig & friends live there.
