External viewers for MIME parts?

[Angel de Vicente]

Hi,

I don't know exactly when this started, but when I receive a mail with a
PDF or JPG attachment, now I get undesired behaviour. Before, when I
opened a PDF attachment (just by pressing RET), evince would open and
show it nicely to me. For a JPEG attachment, eog would do its thing (I'm
in a Ubuntu 11.10 box, with gnus v.5.13).

Now for a PDF, it is shown inline (translated by pdftotext), and for a
JPEG image, ImageMagick is opened (though I cannot see the image). I
would like to go back to the previous behaviour. I looked in the MIME
documentation section of the Gnus manual, but of all the variables
mentioned, I could not see anyone having a value of application/pdf or
image/jpeg. I tried to modify the .mailcap file, but didn't get any
positive results.

I guess I did configure it properly at some point, but some updates
might have broken something, and I forgot what I have to customize.  Any
help on how to configure this properly?

Thanks,
