GnuPG race causes misordered uids?

[Marcus Brinkmann]

Hi,

in the GPGME test suite, one out of a couple dozen runs I see a wrong result
in the keylist tests.

This is because now I check the user ids and other key attributes, and not
always gpg puts the primary user ID first.  I have seen one of the other two
ids being listed first as well.

This doesn't happen very often, and I could not reproduce this outside of
the gpg test suite.  However, I run the test suite with GPGME_DEBUG=3, and
thus I could see that gpg returns the data in that way, and it is not a bug
in GPGME.  This is an excerpt from a normal run:

posix-io.c:59: fd 5: got 1024 bytes
fd 5: got ./pubring.gpg

This is an excerpt from a failing run:

I have also seen Alice being listed first.

I have not the slightest idea what is causing this.

Thanks,
Marcus
