gpg encryption warning

[Colin Baxter]

On gpg encrypting (symmetrical) a file I get the warning:

mouse-minibuffer-check: Wrong type argument: window-valid-p, #<window 40>

after clicking ok in the encryption dialogue buffer. The actual
encryption seems to work, with password and repeat password prompts.  I
am using emacs-25.1.50.1, git-pulled and built today. I do not get the
warning with emacs-24.5.1.

I'm sorry if I've already posted this - I'm having a bad gnus day with lots of
fat finger work.
