- progress information
- overwrite/rename/skip dialog boxes

So the full list is

- progress information; already delegated to a desktop service, kio_uiserver
- password dialog; already delegated to a desktop service, kpasswdserver (kded module)
- overwrite/rename/skip dialog boxes; used to be in kio_uiserver and then I moved them back to kio,
  since modal dialogs in kio_uiserver were a bad idea, apps using uiserver would be blocked
  until the modal dialog is closed. [observer.cpp -r139967 for reference.]
  Maybe the fix is simply to let CopyJob be in kio or kdeui. It's the more low-level jobs
  that are non-gui.
- errors and warnings. I like the idea of an ErrorHandler class that would be derived from
in kdeui (maybe as a singleton instanciated by kapplication, which will be in kdeui,
and which can be instanciated manually otherwise).
