Hi Chris,

For the record, I’ve never experienced this problem (that’s outside of
GNOME) with:

--8<---------------cut here---------------start------------->8---
$ guix package -I '(gnupg|pinentry)'
pinentry	1.0.0	out	/gnu/store/57dg2i4backl38bw4ipcsdg1b7df9j64-pinentry-1.0.0
gnupg	2.1.16	out	/gnu/store/fz44xcp1iksikjvcc472bgsr9hs8ygkq-gnupg-2.1.16
--8<---------------cut here---------------end--------------->8---

ISTR that GNOME has a hack to force its own Pinentry tool.  Could it be
what’s at fault?

Thanks,
Ludo’.
