Can not encrypt or decrypt large files with GPA:

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

After searching the mailing lists with several keywords, I found no
reference to this problem.
If this is not the correct place to ask, please let me know and
point me in the right direction.

>From the command line, I can encrypt or decrypt files with my 4096-
bit RSA key of 6GB or more with no problem (other than painfully
slow).

If I use Seahorse as a right click from Nautilus, I can encrypt
files of any size.
Though Seahorse has a bit of a bug in that it gives the files a pgp
extension and the right click only recognizes files with a gpg
extention for decryption.

Other than the Seahorse extention bug, gpg is working.

With the GPA GUI, if I attempt to decrypt or encrypt a file of say
3GB+, I get a GPA error box
that simply says: /path/filename.gpg: File too large

Is there a work around for this? Do I have something mangled?
