[Pkg-gnupg-maint] Bug#593680: gnupg: segfaults on --list-secret-keys with "list-options show-photos"

[Y Giridhar Appaji Nag]

Package: gnupg
Version: 1.4.10-4
Severity: normal

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

I use a "list-options show-photos" in my gpg.conf and also have a photo as a
UID in my secret keys.  I use "display" from the imagemagick package to view
photo UIDs in GPG.  The problem is that

"gpg --list-secret-keys" segfaults.

"gpg --list-secret-keys --no-show-photos" works OK

"gpg --list-secret-keys --verify-options no-show-photos" segfaults.

Attaching the transcript of a session where this happens.
