I used the ones that Seahorse defaults to:

hkp://pgp.mit.edu:11371
ldap://keyserver.pgp.com
hkp://subkeys.pgp.net

I tried this and it worked. Thanks!

Seahorse seems to be acting a little flaky. I can find this key by its
email address, but not its key ID, apparently.

I had tried rsyncing debian-keyring.gpg and then checking the signature
with that keyring, but it did not work.

rsync -az --progress keyring.debian.org::keyrings/keyrings/debian-keyring.gpg ./debian-keyring.gpg
gpg --keyring ./debian-keyring.gpg --verify SHA512SUMS.sign SHA512SUMS

....which gave me:
gpg: Signature made Sun 27 Jun 2010 09:05:47 PM EDT using RSA key ID 64E6EA7D
gpg: Can't check signature: public key not found
