VLC doesn't shutdown when closed

[Gary Dale <garyndp@gmail.com>]

I'm running Debian/Buster with a Plasma 5 desktop. After I close a VLC 
session, the program continues to lurk in the process list until I send 
it the Kill signal. This is annoying because VLC stops the screen saver 
/ session locker from kicking in while it is active so I have to bring 
up the System Activity monitor to check for and kill all the VLC processes.

Note that just ending the process doesn't work. I need to send the Kill 
signal.
