I'm not sure this is still happening, but looking at the code it doesn't look
like gcry_check_version is being called in gpgv2.
From http://bugs.debian.org/613465:
Running gpgv2 to verify signatures generates a warning in syslog,
gpgv2: Libgcrypt warning: missing initialization - please fix the
application
Verification still works correctly, but the warning is generated every time
gpgv2 tries to carry out an operation.
