Indeed, thanks for the detailed report. It should be fixed now.

When debugging I discovered that KMail uses two KConfig objects that both 
operate on kmailrc. It would be more efficient if you could manage to share a 
single configuration object. I assume that Kmail uses two because one is used 
for the part and one is used for the shell? Maybe KConfig should provide a 
factory for refcounted config objects for such cases?
