GPG bug fix

[elmobp]

Fixes #1082

[laf]

Tested fine.

I do get prompted for the passphrase again when loading oxidized but from what I've found, this is because of gpg2: ueno/ruby-gpgme#11

Unfortunately this breaks the csv processing altogether.

@mikenowak thanks for spotting that. I've just pushed #1113 which fixes this.

@elmobp I think #1113 now breaks gpg support again though, I had a play around trying to get it working but couldn't figure it out - would you mind taking a look?

[elmobp]

Ill have a poke over the weekend!

@elmobp thanks.
