I installed xclip, and it verified what I seem to see. Stuff copied in
falkon does not show up on the clipboard. But, it added to the mystery
a bit. I have three instances of kate running. Copying from #1 instance
of kate DOES show up, but copying from kate #2 or #3 DO NOT show up. If
something is broken, as Ralf suggests, it is broken in a weird way...

You mentioned the "right clipboard" - is there more than one? If so,
what/where is it, and how can I access it?
