Daniel,
Those are the exact steps I'm using.

When I run tag -v on existing tags, I don't see the

-----BEGIN PGP MESSAGE-----

block. It's only present on tags created using the current version.
I've also just upgraded to GnuPG 1.4.10, but the result is the same.
I'm not sure how else I can determine where the problem arises; I'm
using the git and GnuPG versions for OS X built by homebrew, and GnuPG
is happy to use the same key for en/decryption and signing. I've also
verified that none of the subkeys are expired, and that the trust db
is OK.

If you have the tests available, can you try running t7004 to see if it fails
there too?

I rebuilt and installed from source
Passed all 105 tests in t7004-tag.sh
Problem remains with tags I create

This would seem to imply a problem with my key, even though nothing
else is complaining about it.

Here's a very basic way to check: If foo is your tag, do

git cat-file tag foo > a
git cat-file tag foo > a.sig

From the file "a", delete the signature (everything lines between and
including "-----BEGIN/END PGP SIGNATURE-----"), invoking an editor or
your favorite sed/awk/perl magic.

a is the data on which git invoked gpg for signing the tag. (I'm not
sure why gpg can't notice the inline sig directly but that doesn't
matter; maybe because it is none ;))

Now, gpg --verify a.sig should check the signature a.sig for a. Doing
that, maybe with --verbose, you may find out whether the tag object is
bogus or git misunderstands gpg's response. If your key is on a key
server you can also share the file a.sig with us so that we can check.
