I have discovered that with the newest GnuPG 2.1, due to the fact that
the output from the GnuPG has been changed, upon attempt to list the key
(from Gnus in my test case) EPG will fail to return valid list of key,
instead it would crash with args-out-of-range. (Easiest way to get this
error is to attemp to call epa-list-keys.)

After debugging the code, I have discovered that it is trying insert
contents of the output into the list longer than the size of the list. 

While crude workaround, doubling this list (from 15 to 30) has prevented
crash, thus the line 1909 of epg.el would read:

(setq keys (cons (make-vector 30 nil) keys)

Considering the scope of my attempt is to fix the issue so I can send
encrypted/signed E-mail from Gnus, this means that not every function
are verified to work with this change. But I wanted to give you heads up
on this issue.
