I see two different problematic scenarios:

1) select text
2) hit ctrl-shift-c without moving mouse
3) move the mouse and click somewhere so that no text is selected anymore

=> terminal does not respond anymore

1) select text
2) hit ctrl-shift-c without moving mouse
3) hit backspace until you start removing selected characters

=> contents of clipboard is cleared

However, the original wish

1) select text
2) hit ctrl-shift-c without moving mouse
3) hit ctrl-shift-v without moving mouse

seems to work. Is it possible to extend this wishlist bug to also
cover the first two cases? ;-)
