I would vote anyway for hiding the smartcard tab if it has no information, just so that we are not confusing, I can otherwise imagine support questions like: "It says something about smartcards, do I need such a smart card?" As smartcards for crypto is not something generally known by users, i assume.

Just thinking about this, we have at least one customer configuration that uses KXMLGui to hide all smartcard actions and the view. And one other that disables certify actions everywhere. We need to check that this still works with the new details view.

Browsers automatically add an increasing number to the file names of downloaded files in case of a conflict. I think that's a strong indication that people don't like to be bothered with such things. But let's see if people complain.
