[O] org-crypt won't work with new version of gpg

[Eric Abrahamsen]

I'm running arch linux and emacs/org versions below. I had this problem
once before when the gpg package for arch was updated and I had to
repair a symlink in the /usr/bin directory, I think, but now I can't
figure out what's going on. GPG was updated a few days ago, and now when
I go to unencrypt anything I get:

epg--check-error-for-decrypt: peculiar error: "Decryption failed", ""

Which is unhelpful. The 'gpg' command on the command line works fine --
it is symlinked to 'gpg2', which is the real executable. I thought that
when something went wrong earlier it had to do with this symlink being
deleted, but it's there, and still…

I've got `org-crypt-key' set to my private key, and other than that no
real customizations. Any hints very welcome!

Thanks,
Eric
