Bug#806445: seahorse: Adding sub-key to private GPG key results in "General Error"

[Sebastian Scheurer]

Package: seahorse
Version: 3.14.0-2
Severity: normal

Dear Maintainer,

What led up to the situation?
=============================

  Trying to add a sub-key to my private GPG key via the "Gnome keys"
  (a.k.a. seahorse) GUI.


What exactly did you do (or not do) that was effective (or ineffective)?
========================================================================

  1. Open "Passwords and Keys" (seahorse) via Gnome shell
  2. Select GnuPG keys in the sidebar
  3. Select my "Personal PGP key" in the list of keys
  4. Right-click on the selected key entry
  5. Select "Properties" in the context menu.
  6. Select the "Details" tab
  7. Click on "Add" in the "Subkeys" area
  8. Click on "OK" in the appearing "Add subkey to ..." dialog. The
     outcome appears to be the same independent of key type, key length,
     or expiration date (including "Never Expires").


What was the outcome of this action?
====================================

  A message window appears with the message
  ,----
  | Couldn't add subkey
  | General error
  `----
  and a "Close" button. Upon closing the window, the application
  continues to operate without perceivable issues.


What outcome did you expect instead?
====================================

  A new subkey to appear in the list of Subkeys.
