You bet.  At first glance this looked like the bug reporting vector.  Sorry for the noise here!

I just noticed that firegpg can successfully decrypt the message in the copy of the email posted here.  So, it's definitely a problem in the gmail interface specifically.

firegpg can tell that this email was sent with a good signature, and it claims to decrypt it.  However, it does not show any text.  I can save the gpg data into a file and decrypt it with command-line gpg just fine.

Using firegpg 0.7.5, firefox 3.0.7, and gpg 1.4.9, all on fedora 10 i386.

I can decrypt email created with firegpg (sending an encrypted message to myself).  The only difference that jumps out between one sent to myself and the problem email is the header "Content-Disposition: inline"

Let me know if you need any other information :)

Here is the problem email:
