Description of problem:

Assume that one of mail message attachments is a some_picture.jpg JPEG file and mutt read this message and that we are in attachment menu.  Putting a cursor on 'some_picture.jpg' entry and hitting return results in an alert with:

No images found in 'file:///tmp/some_picture.jpg'.

Closer check reveals that mutt does write /tmp/some_picture.jpg but with

image/*; /usr/bin/xdg-open %s

entry in /etc/mailcap fails to handle it.  This does work if /etc/mailcap line is replaced with

image/*; /usr/bin/xdg-open %s ; copiousoutput

The same goes if an attachment is of application/pdf type and the same cure applies.  I strongly suspect that this will be also the case with every MIME type where an external handler is required although I bumped into that with images and checked for PDF too but not for anything else.

Version-Release number of selected component (if applicable):
mutt-1.5.21-7.fc16.x86_64

Additional info:
I know for sure that sometime in the past mutt in Fedora 14 did NOT require 'copiousoutput' and worked without that fine but I cannot tell now if this was the case with the latest F14 updates.  I can confirm, though, that
mutt-1.4.2.2-3.0.2.el5 has not problems with "missing" 'copiousoutput'.  I cannot tell if this change was deliberate; I failed to find anything on this in ChangeLog.
