Bug Description

When starting (or actually closing also) of GNU Privacy Assistant i get the following:

Title [GPA Error]

The GPGME library returned an unexpected error. The error was:
   Unsupported certificate
This is probably a bug in GPA.
GPA will now try to recover from this error.

The issue seems to have been resolved after an update for me.

The Problem here is that ubuntu is shipping a gnome-keyring package that is malicoulsly hjacking the GPG_AGENT_INFO environment variable and thus breaking gnupg2 and software (like GPA using it).
For more information about this see:

Or the gnome-keyring bugreport:

If you unset GPG_AGENT_INFO or set it to the real gpg-agent the issue goes away. (At least for me)
