Unable to change mailcap entry.

[Lloyd Zusman <ljz@asfast.com>]

I'm using the latest (or near-latest) CVS gnus.

For the first time in a couple weeks or so, I tried to view a MIME
image (image/jpeg) that was sent to me ... but now, gnus is trying to
use `ee' as the viewer.  I don't have `ee' and have always used
`display' or `xv' for image viewing in the past.

I'd like to handle this from within `.gnus.el', and so I put the
following into that file:

  (require 'mailcap)

  (mailcap-add-mailcap-entry "image" "jpeg"
			     '((viewer . "xv %s")
			       (type . "image/jpeg")))

... but this has no effect.

The only `mailcap' file on my system is `/etc/mailcap' and it contains
the following entry:

  image/*; /usr/local/bin/display %s

There is no reference to `ee' anywhere on my system except within the
`mailcap.el' gnus source file (it's within an entry in the
`mailcap-mime-data' assoc).

What can I put into `.gnus.el' to force gnus to override `ee' as the
image viewer?

Thanks in advance.
