Nautilus seahorse plugin does not decrypt *.pgp files.

The nautilus seahorse plugin will encrypt files perfectly for me. The problem is that it will not decrypt them. It has not got the .pgp mime type assigned to it.

Decrypting .gpg works fine. Just .pgp does not work.

I spoke with "sadam" on the freenode irc #seahorse channel, who asked me to do the following. He also updated the seahorse cvs appropriatly.

I updated /usr/share/mime-info/seahorse.mime to the following:
-----------------------------------
application/pgp
 ext: gpg pgp asc

application/pgp-encrypted
 ext: gpg pgp asc

application/pgp-signature
 ext: sig

application/pgp-keys
 ext: key keys
-----------------------------------

and then ran the following command:
# sudo update-mime-database /usr/share/mime

Unfortunely, this still did not seem to fix the problem for me, but it did however fix it for sadam. I'm not sure what OS he was using.
I'm using Dapper (installed from beta1 text-install and all updates applied).
