$ git tag -s -F .git/TAG_EDITMSG tag_name

You need a passphrase to unlock the secret key for
user: "Joshua J. Kugler <joshua@xxxxxxxxxxx>"
1024-bit DSA key, ID 14EA086E, created 2009-08-09

gpg: problem with the agent - disabling agent use
error: gpg failed to sign the tag
error: unable to sign the tag
$ echo $?
128

And when I sign at the prompt:

$ gpg -sa

You need a passphrase to unlock the secret key for
user: "Joshua J. Kugler <joshua@xxxxxxxxxxx>"
1024-bit DSA key, ID 14EA086E, created 2009-08-09

gpg: problem with the agent - disabling agent use
Blah blah blah blah

$ echo $?
2

So, it appear that it works (prints the signature) but then exits with 
an error code of 2.

Using --status-log, I get:

[GNUPG:] USERID_HINT EAFD344D14EA086E Joshua J. Kugler 
<joshua@xxxxxxxxxxx>
[GNUPG:] NEED_PASSPHRASE EAFD344D14EA086E EAFD344D14EA086E 17 0

4FE551A1A4AE4DEF7EDD58E1EAFD344D14EA086E

No indication of an error.  The only thing I see that might be an error 
is "gpg: problem with the agent - disabling agent use." But that should 
be a warning, not an error, correct?  I talked with somebody on the 
gnupg IRC channel and they were able to create a signed tag, even 
though they were not using an agent.

Here it is with -bsau:

$ gpg -bsau EAFD344D14EA086E

You need a passphrase to unlock the secret key for
user: "Joshua J. Kugler <joshua@xxxxxxxxxxx>"
1024-bit DSA key, ID 14EA086E, created 2009-08-09

I'm lost. Thanks for the tips.
