GPG signatures using SHA-512 as default instead of SHA-1

[Dabs]

Hi, this is not exactly bitcoin related, but I use this to sign messages (and encrypt some of them.)

Code:

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Is there any possible problem with using SHA-512 to sign my messages?
Can anyone who has GPG / PGP verify this signature and let me know if it's good.

What I want to know is if this is verifiable using the different versions of GPG on different OSes, particularly older GPG versions like 1.4.15, and also Mac and Linux. I know GnuPG on Windows works since that is what I am using.

Edit: If you have a non-windows machine, or if you use an older version (not version 2.) kindly verify this signature and post here that it's good. (You may have to add or trust my public key to make it say it's valid.)

Thanks ralree! I'll be using SHA-512 to sign from now on.

Another gpg 1.4.10 on linux verifies ok here.
