Thanks for testing.

Well, since `q' in epa-key-list-mode is bound to epa-exit-buffer, which
funcalls epa-exit-buffer-function, which is set by default to
quit-window, and the latter kills the buffer if called with a prefix
argument, you could just type `C-u q' instead of `q'.  Or if you want
`q' by itself to kill the buffer, putting either of the following sexps
into your init file should do the trick.

(with-eval-after-load "epa"
  (setq epa-exit-buffer-function
	(lambda () (interactive) (quit-window t))))

(with-eval-after-load "epa"
  (define-key epa-key-list-mode-map "q"
    (lambda () (interactive) (quit-window t))))

The latter affects only epa-key-list-mode, while the former has wider
scope, since epa-exit-buffer-function is used in several places in
epa.el.
