This works for me.

$ cp /etc/mc/mc.ext ~/.config/mc/

$ sed -i 's/\/usr\/libexec\/mc\/ext.d\/doc.sh open pdf/\
xpdf ${MC_EXT_FILENAME} >\/dev\/null 2>\&1 \&/g' ~/.config/mc/mc.ext

$ grep xpdf ~/.config/mc/mc.ext
xpdf ${MC_EXT_FILENAME} >/dev/null 2>&1 &

If this doesn't work for you, start over with a clean user environment.
