I have no mailcap in my home directory and /etc/mailcap says:

application/pdf; /usr/bin/xdg-open %s

xdg-open works. I have tried it from the terminal with an existing PDF
on my hard disk. xdg-open starts evince and shows the PDF.

So the mime hook should be OK.

The log says:

lstat("/tmp/emm.32836CK/.#fellowship_posters_4_2_pf.pdf", 0x7fff016bb970) = -1 ENOENT (No such file or directory)

so the problem seems to be that Gnus doesn't copy the file from the imap
server to the local /tmp directory before calling xdg-open on it.
