In fact, gpg doesn't have a way to return the name of the keyrings
that it is using by default.  You have to figure it out from the
configuration file.  I haven't checked it out, but those filenames
could even be relative instead of absolute, adding another complication.

GPGME doesn't allow the specification of extra keyring files, and thus
I don't see how you could allow it in the application, unless you are
mixing GPGME with your own gpg invocations.  The latter is possible,
but can lead to inconsistencies as you describe quite naturally.  Also
for example that a key can be found in the "with extra keyrings gpg
invocation", but not with GPGME operations.

It is our opinion that keyring settings are a crypto engine
configuration that should be done in gpg.conf (thus setting it for all
applications).  If you need total control over the crypto backend, you
can from 1.1.x on create a separate .gnupg home directory and activate
it on a per-gpgme context (or per application) with
