When I copy something from another window then my terminal and want to paste it into my terminal (on the command line) the paste option in Edit is grayed out. `Ctrl`+`V` does not work in GNOME Terminal 2.29.6.

I try to copy form netbeans into a terminal. If I paste it somewhere else, in gedit for example, it gets pasted. So it is copied. 

Using `Ctrl`+`Shift`+`C`/`V` does not work.

Is this a settings of from some sort?
