epa when using emacs daemon / delaying function call until after emacsclient frame is opened

Context: I run emacs as a daemon.

Problem: I have an emacs module (gmail-notifier) loading on emacs-startup in
my .emacs which makes reference to a private file stored as a .gpg. Since
this tries to load on start-up, it asks for the encryption password on
startup. The problem with this is (1) it doesn't actually work: for some
reason I get a "wrong number of arguments error" and (2) even if it did
work, it would be inconvenient, since I have the emacs daemon autoload on
boot-up.

What would seem ideal is to only have the .gpg loaded once an emacsclient
frame is opened. This page (
http://splash-of-open-sauce.blogspot.com/2011/02/securing-your-private-email-credentials_7309.html)
discusses a similar situation, and suggests doing something like this:

(defun load-secure-config(frame)
   (require 'my-config "my-config.gpg"))


 (add-hook 'after-make-frame-functions 'load-secure-config)

Essentially putting the reference to the .gpg file in a function which
is only called once the "make-frame-functions" have run.

This seems like a good solution but didn't work for me. Using it
resulted in emacs completely freezing as soon as I opened an
emacsclient frame.

Is there another way of delaying the calling of a function until after
an emacsclient is opened?

Just FYI that was my article and I ended up giving up.... Weak I know ;)
I start emacs daemon when I first start emacs and use the gpg agent and
gtk-pinentry.

That's unfortunate. I'm just manually calling the function that needs to
look at the gpg file after I open up an emacs frame (which is very
non-ideal). There must be some way of making this work, I would think.

If you dont need it until you open a frame then it should be easy but
that said I am guessing you are starting emacs as you login for a
reason and the timing is the issue if you need to open the gpg to get
passwords for "daemon"y things. I found issues with gpg-agent and
keychain when starting emacs automatically. Best of luck anyway!
