Description

gpg: Fix attempt to double free an UID structure.

* g10/getkey.c (get_best_pubkey_byname): Set released .UID to NULL.

Phil Pennock reported an assertion failure when doing

% gpg --auto-key-locate dane --locate-keys someone
gpg: Ohhhh jeeee: Assertion "uid->ref > 0" in \
       free_user_id failed (free-packet.c:310)

on his keyring. This patch is not tested but a good guess.
