A feature or a bug i suppose. What you are seeing are the effects of the
modifyOtherKeys feature of Vim and xterm (see :h modifyOtherKeys).

I am not sure why it happens for you when pressing CTRL-V in command
line mode, it does work for me as expected, unless you accidentally
pressed Shift-Ctrl-V instead of Ctrl-V

To disable it, set the t_TI and t_TE terminal settings to the empty
string:

let &t_TI=""
let &t_TE=""


Best,
