I start from 'emacs -Q' and I create an empty, encrypted tar file,
insert a file into it, and save it like so:

C-x C-f n e w . t a r . g p g <RET> I h e l l o . t x t <RET> C-x
C-s C-s O K <RET> <RET>

At this point, I enter a symmetric key from an external popup dialog:

t h i n g <RET> t h i n g <RET>

I then continue in emacs:

q C-x k <RET>

I open the encrypted tar file like so:

C-x C-f n e w . t a r . g p g <RET>

GPG Agent decrypts the file. What I expect to find is a buffer in
tar-mode, but I instead find a buffer in Fundamental mode with the
following message:

File mode specification error: (error Malformed Tar header)

Instead of a tar file encrypted with GPG, I instead have an encrypted
ASCII file with the same text as what was in the tar-mode buffer.
