I am using Debian 8 on all platforms and sadly have gpg (1.4.18-7+deb8u3)
and gpg2 (2.0.26-6+deb8u1). I am using both (gpg for mutt and gpg2 for
Icedove/Thunderbird), because gpg2 relies on pinentry which completely
breaks one of my workflows. I use gpg2 for key management though.

I tried that already, will try it again. I also suspect
old/"broken"/unusable keys.
