I'm running unity in Ubuntu 13.04, which still is sorta descended from
gnome.  Neither xdg-open nor gnome-open seems to work (if I'm doing
this right in dired: navigate to a pdf/html file, type &, enter
xdg-open).

I have the feeling the problem is in emacs, org-open-file, or their
interaction.  It's definitely not in xdg-open/gnome-open themselves,
as they work fine from the command-line with M-! .

thanks guys,
Matt
