If you keep using ~/.gnupg/pubring.gpg, I think this is the cause of
your problem.

In this case, see this comment in the bug tracker of GnuPG:

	https://dev.gnupg.org/T5409#145906

To excerpt the solution from the comment, it's:
--------------------------
cd ~/.gnupg
gpg --export-options backup --export >allkeys.gpg
mv pubring.gpg pubring.gpg-saved
gpg --import-options restore --import <allkeys.gpg
rm allkeys.gpg
--------------------------
