The UI is also screwed, if the core already does the error handling and 
doesn't tell the UI about it. 

What about throwing exceptions and letting the UI show the messageboxes? :-] 

Or, if we don't want to use exceptions, have some other means of error 
propagation, like an abstract ErrorHandler being passed around. That would 
get ugly, though.

As a last resort, KNotify could be used for displaying errors. Or did 
KNotifyClient (or whatever it's called right now) end up in kdeui by now?
