I fixed the slotInfoMessage warning a better way (moving the slot to the
private class since it's unrelated to the one in the base class; I'll commit tomorrow),
but I didn't have a fix for addSubjob/removeSubjob so I'm glad you raise this.
Your post made me realize the argument-type difference... the fact that addSubjob 
takes a KIO::Job and removeSubjob takes a KJob is quite illogical.
I would use KJob for both (since it's virtual anyway) and I would handle 
that correctly in the code (calling the KJob:: methods and not doing the
KIO-specific stuff). I.e. allowing normal KJobs as children of KIO::Jobs instead
of half-forbidding like now. Can you make that change?
